We can see the bottom of our pond!!
We are using a Koenders Water Solutions 16 ft Single Diaphragm Windmill System as well as Nature’s Pond Conditioner and Dye to keep our swimming pond clean and clear and we can see the bottom at 16 ft deep.

New Pond Doing Well
We just dug the pond in the winter of 2017 and used it for the first time in the summer of 2018.
Andrew and Doug (Pond Specialists) were very helpful in creating a maintenance schedule to ensure the pond lasts a long time.
The pond stayed a nice blue all summer with a few weeds starting when the dye was getting dimmer. This was mentioned to Andrew and we are now adjusting our dye application by applying it in more often but less. We had probably put too much at the beginning instead of spreading out the first application. Our pond is still in the very early stages. This year will really tell us how the product is working following a more spread out dye schedule.
Blair and his family fishing in the Winter!
Here are photos of winter fishing trout pond. We keep the trout healthy throughout the winter with Koenders Aeration System and we treat the pond in September with Nature’s Pond Conditioner to clean water up before freeze up so the fish stay healthy all winter.

The Nature’s Pond Conditioner works Very, Very well.
We are very happy with the product. We also have one of your aeration windmills and pond rakes. Before putting in the Natures’ Pond Conditioner we had a record year of Algae in our pond, all over and thick. The year after using Nature’s Pond Conditioner along with raking out the algae as well, we have had our record year of the pond being the healthiest it has been. The algae was so bad before I can begin to describe it.
The Koender’s Aeration windmill has impressed me
I have been on the nature’s pond care program of for about 2 years now, using the Koender’s Double Diaphragm windmill aeration system and Nature’s Pond Conditioner as well as the Nature’s Pond dye and I am very happy with the results. The algae is almost eliminated and the pond weeds have been reduced significantly, where the pond weeds once went 15-20ft from the shoreline are now only 3.5ft from the shoreline. The Koender’s Aeration windmill has impressed me on how well it has kept the ice off the pond in the cold winter months, not to mention, it’s been virtually maintenance free

Fish kept healthy during the Winter
During the Winter, we use Koenders Dual Diaphragm Windmill for aeration with 2 airstones and Nature’s Pond Conditioner. It keeps the fish nice and healthy all seasons. We use the pond for fishing and also swimming in the Summer. We’re really happy with everything.

Steven is Impressed!!
The season was pretty good for the health of the pond. I am really impressed with the aeration and pond dyes and conditioner. Definitely made a difference in the water quality and shear beauty.
Steven in Quebec, October 2018
See before and after pictures below.
I am amazed how well it cleaned up my pond!
The Koenders Water Solutions 3 Step Plan works great!
For 5 years I had been battling with my pond trying to get it clean and healthy. I tried all the different pond chemicals on the market, although they did get rid of the algae initially, it always came back stronger shortly after, it was a short term fix. I finally got my pond under control when I heard about the Koenders Water Solutions 3 step plan, which includes raking away as much of the algae as possible with one of their easy to use pond rakes-I did a little bit at a time when the wind pushed the algae to the side of the pond. I added their Nature’s Pond Conditioner and set up a Koenders Aeration Windmill. The Aeration windmill I set up approx 800ft from my pond, where I thought It would get the most wind-and it is always turning (my pond is in a bit of a valley).
I have provided before and after photos, the after photos are only 60 days after being on the Koenders 3 Step Program and the algae hasn’t come back. Needless to say I am impressed. As well the before photos were taken after I had been on the program for a bit and reduced the algae. The algae initially covered around 40% of the pond.

Koenders Water Solutions/Nature’ Pond Care 3 step program is Amazing!!
When something sounds to easy to be true it probably is!!! That is why when I was told about Nature’s Pond Care 3 step program and the fact that it would not be an overnight success but more a process I started to believe!!!
I have a small landscaping business and one of my customers asked me If I would help them get rid of all the duckweek in the pond, as they have a really nice house and well-kept yard, except for the pond which was a disaster, completely covered in duckweed. They tried several things that promised quick results but could not find anything that would clear it up and keep it clear, not to mention the rotten egg smell that came from it.
I spoke with one of pond consultants at Koenders Water Solutions Inc., at which time he had asked a lot of questions about the pond in order to determine the best method to treat it. He called it the Nature’s Pond Care program that consisted of a 3 step plan, which includes: “revive” (with bottom up aeration), “removal” (with a speically designed pond cutter and rake) and “renew” (with Nature’s Pond Conditioner).
We started the 3 step program in Sept 2017, when the pond was completely covered with duckweed. As you can see in the pictures I have provided (the only opening was where the aeration bubbles were coming up) and then approx. 2 month later the pond was almost completely clear, the owner has also indicated that the rotten egg smell is gone and that the water has never been more clear. He is very happy with the results, which reflects well on me as his landscaper and he now plans to add fish In this spring and start using his pond for recreation.

Koenders Water Solutions – Nature’s Pond Care Team,
We have a pond on our acreage that we use for house water and irrigation. The pond is approximately 100 FT in diameter and 12-15 ft deep.
This pond has always given us problems – the water would get smelly and the pond would be full of algae and weeds to a point that it would clog up all the filters going into the house. We had the hardest time maintaining this body of water and having a steady supply of useable house water that would not smell up the house and make our clothes all gray.
That was until the last couple of years when we started following the Nature’s Pond Care program. We installed a Koenders Electric Aeration System in the pond and started treating the water with Nature’s Pond Conditioner – the Spring/Summer formulation in summer and then the Fall/Winter blend in the early spring when the water was still cold. We also treated it one last time in the fall before winter freeze up.
The water has never been cleaner. What a huge improvement to the past. The water does not smell and we don’t have to worry about clogged filters for the pond is clean and clear now.
Great products -thanks!
Nature’s Pond Care Program Works Great!!
Over 7 years ago we started using your Nature’s Pond Care program. We have a fish pond with some beautiful rainbow trout in it and the body of water is approx 1 acre in size with an average depth of 12 ft.
Our pond was having issues with algae and weeds and so we wanted to make sure it was clean and healthy especially for the fish. We installed a Koenders Dual Diaphragm Windmill Aeration System and began our treatments of Nature’s Pond Conditioner Spring Summer Blend in late Spring/Early Summer and then we treated it with 5 gal of Nature’s Pond Conditioner Fall/Winter blend in the Fall.
Our Pond has been clean and clear ever since. One year we did forget to get our treatments in the pond and all of a sudden the water started turning an awful green color. It did not take us long to remember what we needed to do. Within 7-10 days of our treatment with Nature’s Pond Conditioner, the pond was back looking healthy and clean again.
As for our windmill aeration system. It aerates the pond all year round. It is working well and we have done nothing to it during all this time. It just keeps pumping air into the pond!!. Great product and it costs us nothing to run.
We are very happy with the products, the results and the service!

Your Products Never Stop Working !
We have a fish pond full of cat fish, bass, crappie and blue gill so it’s important that we keep our water healthy and clean so that we do not get disease spread or fish kill.
We turned to Koenders Water Solution products about 16 years ago, to help us ensure that our pond remains clean and fish healthy.
We installed a Koenders Windmill Aeration system way back then and have never done a thing to it. It has been an extremely reliable and effective product and we are very happy with the results.
Nature’s Pond Conditioner and Koenders Windmill Aeration – a truly effective combination!
I am a farmer who, in the last few years have decided to slow down on farming. My son now works the farm. To keep me busy, I decided a few years back to dig out a 2 acre pond so I could relax and enjoy.
We installed a Koenders Windmill Aeration system to aerate the pond which did just great. We found though that we would still get a septic tank smell in the pond, along with an ugly brown color which prevented us from swimming and having fun in the pond.
We have a lot of run off and leaves coming into the water and figured that the aeration needed some additional help to clean up the water, so we decided to treat the water with Nature’s Pond Conditioner and use it in combination with the aeration windmill.
Did it ever make a difference! The pond dye in your formula turns the pond a deep blue, green color keeping the natural beauty of the water and not turning it some terrible fake blue color.
The blend of bacteria eats up all the leaves that are falling into the pond caused by all the trees on one side of the water. The conditioner seems to break up and consume all the leaves and other sludge in the bottom of the pond and it makes the water healthy and clear. It also gets rid of that awful smell.
Every year since, we’ve used your pond conditioner in combination with the Windmill and it works great!!!
Clean, healthy water and no more fish kill!
We installed a Koenders Windmill Aeration System on our fish pond almost 20 years ago. Ourselves and everyone else around us were experiencing large fish kills and we wanted to put an end to it.
Since installing our windmill aeration system we have never had a fish kill. The other benefit of having our windmill aerating our water is that it helps keep the water healthy and clean. We do get some aquatic vegetation so we have used your Nature’s Pond Conditioner as well. Works well in combination with the aeration and its all natural which is great so we don’t have to worry about it harming our fish.
Thanks for your great products and commitment to nature!!!
A joy to own this windmill
I just want you to know what a joy this windmill has been to own…for its durability and how it improves the health of my pond. It’s been standing here 7-8 years and I’ve done nothing to it. So I don’t feel bad about having to finally replace the diaphragm now. Thanks again.
Our Koenders Windmill “Works Like A Champ!!!”
We have a 1 acre fish pond that had been giving us a lot of problems. The pond would be full of milfoil and duck weed every year and after wrestling with this pond for several years, we decided to purchase a Koenders Windmill Aeration System.
Within 90 days we started seeing our pond clearing up. Our pond is now stocked with bass, blue gill, crappie and trout and the windmill aeration has done a fabulous job of keeping these fish healthy and clean.
Thanks for a great product that has been working flawlessly since we installed it !
Happy with our purchase!
Our pond is about 35 years old and just a little under a 1/2 acre in size. It sits out in the open with very few trees around and is in a fairly windy area. We had an old windmill aeration system that was already in place when we moved in and it worked ok, but not all that great. At one point in time our pond was filled with blue gills. We have our pond stocked with some bass, catfish and gamers. We don’t fish for them, but treat them more like pets.
In July of 2015, we decided it was time for a new windmill. We chose to go with Koenders and purchased a 12-foot single diaphragm windmill system. My son and I found it very easy and straight forward to set up. We poured some good concrete anchors and that thing has been pumping so well since day one! We had some extremely windy days this past winter and our windmill is still standing tall. We are very happy with our purchase and we trust in our Koenders windmill to keep our pond healthy and our fish alive!
No more fish kills!
I constructed my pond in the late 1980’s with my father, and made it about 1/3 of an acre in size. We wanted it for fishing, recreation and swimming, so have stocked it over the years with a variety of different fish such as blue gill, crappie and catfish.
We noticed that we would lose some of our fish each year during the hot months of July and August. IN 2006 we finally decided it was time to address that problem and we installed a Koenders Windmill Aeration System.
We ordered it up and it was delivered quickly. One of my neighbors and I spent a couple of evenings assembling the tower and getting it all set up, and it has been running fine ever since! Besides routine maintenance on the diaphragm we haven’t had to do anything to it. The windmill keeps a hole in the ice for the fish throughout the winter and we haven’t experienced any more fish kills since installing!
Pond Study: Nature’s Pond Care Program is a clear winner!
We are a crop farmer of canola and lentils in Saskatchewan, Canada. To irrigate our crops we draw water from two surface ponds/dugouts on our farm, and each pond holds over 1 million gallons of water.
Last year we conducted a study on the farm. On one pond we followed your Nature’s Pond care program by installing a Koenders Windmill Aeration system and treating the water with Natures Pond Conditioner. We did not do anything to the other pond.
The difference between the ponds was miraculous!!!
The pond that we selected to treat was crystal clear and no longer murky at all. We did not have any issues with our sprayers which in the past were clogging all the time. Our crops were healthy and harvest went along smoothly.
As for the other pond that we did not choose to treat, it was a worse mess than usual! The algae and weeds were so bad that we could not even suck water out of the pond. The constant plugging of filters became too onerous and we decided to only use the pond that we treated with your Nature’s Pond Care program.
We just purchased our Nature’s Pond Conditioner for 2017 and will be looking at another windmill to install on this 2nd pond.
Mike Deobald, Stone Barn Farm
We have a ½ acre pond that is mostly used to enhance the beauty of our property, and we have bass and bluegill that call our pond home. In 2002 we decided to add a Koenders windmill aeration system to help keep our fish and pond healthy. We found that the windmill was very easy to assemble and were quickly pumping oxygen into our pond! During the cold winter months the windmill has kept a 15 foot area of the pond from freezing over, and has really cut down on any chance of fish kill. We have “Chicago” style weather here, with a lot of wind, a lot of cold, and a lot of sun. One of the best things that we have found about our windmill is that we haven’t had to perform any sort of maintenance in the entire 15 years that we have owned it!
Honestly one of the best things we have ever bought!
We have 2 ponds about 20 years old, and about 10-12 years ago we decided to purchase a Koenders windmill aeration system for our smaller pond. It has honestly been one of the best things that we have ever bought! If you follow the directions and be sure to anchor it down properly it works absolutely perfectly. We have many types of fish including walleye, northern pike, small mouth and large mouth bass, as well as crappie and bluegill. The added oxygen is crucial to keep them alive and healthy. Over the winter months there has always been an opening in the ice about 20 – 25 feet in diameter.
Shortly after we installed our first windmill, my father-in-law decided that he wanted one too. His has been working perfectly ever since it was installed. Other than replacing some hose because the muskrats had chewed through it, neither of us have had to do anything to our windmills other than a little bit of grease. Our ponds are used a lot with kids and grandkids fishing, swimming, kayaking and paddle boarding. We are very happy with our Koenders windmills and wold recommend them to anybody!
The program has outstanding results!
I have been using the Nature’s Pond Program for a little over a year now and the results are outstanding! Every year I used to have to rake off all the floating mossy looking algae (filamentous algae) and it wasn’t easy as there was algae from about 6 feet out and beyond covering the entire surface of the water. I would have to wait for windy day until it would float near the edge of the pond and then hall it off, which isn’t fun nor easy. I know I have a problem pond, as it is next to neighbouring cattle farms which really creates an excess of nutrients in the pond that results in my water quality issues.
I was talking to my uncle one day that also has a pond and was explaining to him the problems with my pond and the work involved to keep it clean. He had recommended that I try Nature’s Pond Conditioner as it had worked wonders for his pond and I am SO glad he did, the Nature’s Pond Conditioner works great! I went from having an algae covered pond to almost no algae. I just bought another bottle of Nature’s Pond Conditioner today, and I plan to add Nature’s Pond Conditioner each year to prevent the algae from coming back.

Windmill has been running since 1989!!
In 1989 we purchased our first Koenders windmill which was installed to aerate our fish pond that we had dug out a year earlier. This windmill has worked so well that we even bought another one off a fellow that had installed one of these windmills in the middle of a forest. He told me that it did not work very well. I explained to him that you need it to catch the wind in order for it to work well and that the middle of the forest is not such a great place to have a windmill installed.
So I ended up with two of these windmills aerating my fish pond and we have never had any issues with the water. The fish have always stayed healthy and we have never had a fish kill! Our Koenders windmills have been working amazing and they just keep running like a champ. The only maintenance that we have done is simply changed the diaphragms on them every 7-10 years. I will stand behind your products no matter what. They last forever!!
Thanks for the great service and support over the years. Your team is knowledgeable, friendly and passionate about what you do.

One reliable windmill!
17 years ago we dug our first pond, about 1.5 acres. It sits out in the open with very few trees around and gets full sun for most of the day. Once it was filled it was beautiful to see! After having the pond for two years, we decided that is was time to invest in a windmill aeration system. We went with the Koenders 16’single diaphragm model and have never been more happy. In the past fifteen years we have only ever had to replace the diaphragm once. The original diaphragm had lasted for thirteen years before we finally had to do any sort of maintenance. That is one reliable windmill! That same windmill is still turning today pumping oxygen into our pond to help keep the fish healthy and the weeds and algae to a minimum. We have stocked the pond over the years with crappie, bass and bluegill as we have always enjoyed fishing and swimming in our pond. The kids have all grown up now, but we are waiting on the grandkids to enjoy the pond in the same way. The windmill has never let us down and is quite attractive to look at. We love it!!
Extremely happy with our worry-free windmill!
We have had a Koenders dual diaphragm windmill aeration system installed for about 5 years now. The pond was dug about ten years ago, and is located in natural woodland area on our property. There are some large trees and natural shrubs that surround the pond and are homes for a variety of birds that visit the pond such as herons and wood ducks. We have stocked the pond over the years with a few different types of fish that the kids really enjoy trying to catch. The pond is surrounded by a berm to help keep agricultural run off from entering the water. We are extremely happy with the quality of our windmill and how worry free it has been. We haven’t had to do any sort of maintenance or repairs on it in the entire time that we have owned it. It seems to effortlessly pump air through the two airstone diffusers keeping our fish healthy and water clean!
City of Ottawa
The City of Ottawa is proud of one of its most noteworthy parks, Andrew Hayden Park named after the former Reeve of Nepean. Andrew Haydon Park is a relatively large Ottawa park, stretching for roughly a kilometer in its longest dimension – east north-east to west south-west by roughly 300 meters across stretching between Carling Avenue and the Ottawa River. The park includes multiple streams and two interior ponds one of which is close to 2 acres in size and a true landmark of the park.
During the winter months the park is relatively quiet but when summer comes along the park comes alive hosting many summer activities with it variety of facilities. The ponds are an important feature of the park and they play host to such things as radio-controlled model sailboat trials and races, family BBQs around the water, recreational games and sunbathing, and children play on the structures that have been installed for their enjoyment. With picnicking, open water and trash cans this park is also a popular hang out for Canada Geese, Seagulls and other birds.
We are proud of this park and the mini-lakes adjacent to the Ottawa River play a big role in the attraction of this location. That’s why its so important to keep these ponds healthy and clean. We get a lot of leaves, bird waste, fertilizer, grass clippings and other run off into these bodies of water and its important that we have an environmentally friendly program to keep them healthy and clean.
We chose to work with Koenders Water Solutions Inc and have been following their Nature’s Pond Care program for the last few years with outstanding results. First, we installed one of their windmill aeration systems which has been a really nice feature of the park. It not only looks really pretty sitting on the edge of the Ottawa River between the big pond and the river but it also serves a dual function of aerating the pond that is almost 2 acres in size. This windmill aeration system does not require electricity to operate and runs 365 days per/yr with no operating costs and very little maintenance.
Another real bonus to having the windmill aeration system working all year round is the fact that it keeps an area of the pond open in the winter and oxygen flowing throughout the pond. This has ensured that we do not get a fish kill in the pond for we have many species of fish living in the water.
We also treat the pond with Nature’s pond products which our manufactured by Koenders Water Solutions Inc, these are natural pond treatments that are made up of ingredients that are safe for humans, fish, animals and the environment. The treatments consists of beneficial bacteria and enzymes that break down and consume the organic matter that enter our ponds keeping them healthy and clean. These treatments ensure that their is very little sludge build up and they keep the water clean and clear. There are no smelly odors coming from the water and with the clear water we are reducing mosquitoes in the area. Mosquitoes tend not to lay their larvae in healthy ponds because if they do the fish can see the eggs and they consume them.
I really noticed how the leaves that used to accumulate all around the edges of the pond are now just broken down and chewed up by our pond care program. Its been a real pleasure working with Koenders and we look forward to continuing our partnership.

So pleased with my windmill!
I am very pleased so far with the performance of my Koenders Windmill Aeration System. I have a 20 foot tower design, single diaphragm compressor that has continuously pumping air into my pond for the past 5 years. My pond is roughly 1 acre in size and we use it for fishing and swimming. In the entire 5 years of owning my windmill, I have never had any issues. It works perfectly all of the time. It turns smoothly, it pumps smoothly, it is great to look at, and I have never once had to service it at all!
We love our windmill!
12 years ago we dug our own fish pond. It is 1/2 acre in size and up to 15 ft deep in some places. We designed it with an island in the middle and water on all sides. We immediately installed a Koenders Windmill that has been running for 12 years straight with absolutely no maintenance, and have now just recently ordered a maintenance repair kit.
We stock our pond with bass, perch and blue gill and we have enjoyed how the pond brings us closer to nature. Our pond remains healthy and clean and we have never had a fish kill during all these years. We are very satisfied with the performance of our Koenders Windmill and has certainly lived up to its expectations.
Your program cleaned our pond in 30 days!
Before using Koenders double diaphragm aeration windmill and Natures Pond Conditioner my pond had a thick layer of algae growth 2 inches below the surface. As well, the water was turning black, as it was becoming septic. About 30 days after pouring in Koender’s Nature’s Pond Conditioner and getting the Koenders double diaphragm aeration windmill set-up and working, the water cleared right up, my pond water is clear now, it was phenomenal!.

Your windmill keeps our fish healthy!
Our pond is an oval shape about one half acre in size, and we have it stocked with bass and bluegills. There are a few trees around the edge of the pond and it is very pretty to look at! We have a 16 ft single diaphragm Koenders windmill aeration system installed about one hundred and fifty yards from the pond up on a small hill. We have had our windmill for the past 12 years and it has never let us down. It is constructed of galvanized steel and has not shown any signs of rust whatsoever over all these years. We often invite different church groups, boy scouts, girls scouts and others to come and camp out around our pond. Our favorite part is to watch them catch fish from our pond and then clean them and cook them over an open fire. We are so happy with our Koenders windmill that provides our fish with the oxygen that they need to remain healthy, growing and reproducing.
We have a lovely spring fed pond that is about ¾ acres in size, and the water that enters the pond is cool and clear. We have our pond stocked with fish, mostly with bluegills and bass which we enjoy for fishing. We have used a Koenders 12 foot single diaphragm windmill aeration system for the past 14 years to add important oxygen into our pond to keep our fish alive and healthy. In 2008 a very heavy windstorm blew through our region with the winds were gusting up to 100 mph. There were trees that were blown over and barns as well, and unfortunately our windmill got blown over too. Luckily after the storm had passed we realized that the only damage to the windmill was a few bent fan blades! We easily ordered replacement blades and a maintenance kit for the compressor just in case. We got great customer service, our order was easy to place and was shipped out right away. We replaced the bent blades and easily installed the new diaphragm and other components that were included with the maintenance kit. We stood the windmill back up, and still to this day it is working the same way it did when it was new! We are very pleased with the simple operation and efficiency that we get from our Koenders windmill aeration system.

We love our current windmill so much we bought another one!
We have had a Koenders windmill up and running for nearly 20 years. It has been the best way to provide oxygen to our pond that is close to 2 acres in size. When we stocked our pond with fish, our Koenders windmill aeration system never failed us. It kept the pond well aerated during both the hot summer months and the freezing cold winter months, while many of our neighbors and fellow fish pond owners would experience massive fish kills. We are really excited about our NEW Koenders windmill that we have just purchased. If it can last even half as long as our old one we will be very pleased. We have had so many joyful years from using a Koenders windmill that we highly recommend your products to our neighbors and friends.
So happy with our purchase!
We really enjoy our Koenders windmill, it looks beautiful in our yard next to our pond and we have gotten many compliments on it. Before assembling it I just spray painted the blades and tail with Tremclad primer and paint and it is holding up really well to the elements. We live in a windy location so our pond is constantly getting aerated and the water is always clear. We are very happy with our purchase!

Koenders Water Solutions,
We installed one of your Koenders Windmill Aeration Systems over 15 years ago. We use it to aerate our 2 acre fish pond and it has done everything it was promised it would do. Since installing this windmill we have never had a fish die off and it has been working amazing year round for all these years.
I expected that we would have done some sort of maintenance to this windmill a long time ago but it has just kept pumping air all this time so we have done nothing to it until recently.
Thanks for delivering on more than what you promised!!
Dear Koenders Water Solutions Inc
Koenders Windmills Work Amazing!!!
I have owned a Koenders Windmill for over 10 years and it has been working really well ever since I installed it!!!
It aerates our 1/2 acre fish pond that has blue gill, catfish and bass stocked. This windmill aeration system has done a really good job of keeping algae and weeds from accumulating in our pond and it keeps the fish healthy and strong. We have never had a fish kill for over 10 years since the windmill went into action.
Not only have we saved money on electricity by using this windmill to aerate instead of electricity but we have never had to do anything to it. It was only recently we performed maintenance on the compressor by changing out the diaphragm. Pretty amazing after 10 years!!!
Park Hills, MO
I just wanted to thank you for making a great product. I purchased one of your windmills – summer of 2014 – and for various reasons did not get it set up until June of 2015 – and then had some health issues during the winter of 2015/16 and did not get the freeze control unit installed so “it froze up” (I’m in central Wisconsin) – thus I had no air “pumping” – so your people advised me to get a “maintenance kit” – which had a new diaphragm and various other parts in it. A friend helped me install that “kit” yesterday – and as soon as we got it back together we had air pumping – Wonderful. I really don’t know what part did it as the old diaphragm “looked” ok but maybe it was not – or it was one of the other parts. I believe the issue was due to the freeze up causing too much back pressure – but what “blew” I don’t know – but do know now – it’s working again. Thank You.

I am Happy With Product, Real Happy!!
We have been aerating our fish pond with a Koenders Windmil for over 20 years. This pond water was used for crop irrigation until I retired now it is just used for fishing. My grandchildren love to come over and fish for the Bass, Bluegill and Perch that are stocked in the water.
The windmill aeration keeps the fish healthy and pond clear – you can see down 2-3 ft deep into the water. The only thing I have done in the way of maintenance with this windmill is changed out the diaphragm and check valves a few times so I can’t complain one bit. This product has done me good.
See for yourself why Koenders Windmills are the best! This low-wind fish farm** set up their windmill and it is amazing to see how much oxygen is being produced. It’s easy to see how Koenders produces more cubic feet per month of oxygen then any other brand!

Two Koenders Windmills for over 15 Years!!!
We installed two of your Koenders Windmill Aeration Systems over 15 years ago to help pump oxygen into our trout ponds. They have been running just like the way they were the day I installed them. One of them I have done nothing to at all, it just keeps pumping air like it was new, the other one has been doing a good job too but I have had to change the diaphragm on it at the 12 year mark.
It is cold in the winter months and hot in the summer here in Colorado and these windmills have done a pretty darn good job of keeping our ponds clean and fish healthy, especially in the colder winter months when there is ice on the water.

Companies Posing to Sell Koenders Parts or Products,
I wanted to let you know that there are companies in the market that are advertising under your company’s name when you search the internet for your Koenders Windmills products. I ended up calling one of these companies and asked if they were selling Koenders “Genuine Parts” which they led me to believe they were. Each time I asked the question, the representative on the phone replied with a confusing answer. I should have know better!!!
I bought the parts and sure enough they were not Koenders “Genuine Parts”. They were some brand that was posing to have the same parts as your or would work with your products.
Well these parts did not work and did not fit. They charged me close to $ 500 for these parts. Thankfully, I was able to order these parts from you and still hoping to get my money back for the other parts that did not work.
I am writing this note to you so that you can make sure to warn your other customers about this so that they don’t have to go through the same trouble that I just did.
Its always tough being the leader in the market because these types of companies try to grab on to the success that you have created!! Thanks again for a really great product!!
So impressed with your windmills – just bought another one!
It is very important for us to have clean and healthy water as we use our pond to train dogs on retrieving items from the water. We installed a Koenders Windmill Aeration System about 10 years ago on this pond and our water is in beautiful condition. This whole time we have never once had to do any maintenance to the windmill so it has definitely impressed us and lived up to our expectations!
We have another pond which has not been used for training and does not have one of your windmills installed on it. This pond is a mess and full of weeds and algae! We are looking forward to installing another one of your windmills on it so that it can clean up this pond as well as the other one has done.

Windmill Pumping for 10 Years Straight with No Real Maintenance!!
We installed one of your Koenders Windmill aeration systems about 10 years ago to keep our fish alive in a 2.5 acre pond we have on the farm. Never had a fish kill since and this windmill has helped both keep our pond water clean and fish healthy.
We have never had one issue with the windmill during all this time and no real maintenance so to speak of except for an annual greasing of the support cone and cleaning of the airstone diffusers that we have in the water.

Can Now See Right to the Bottom!!
We have a 3/4 acre pond on our acreage here north of Toronto, Ontario. Six years ago we decided to install a Koenders Dual Diaphragm Windmill Aeration system in our pond because we were tired of seeing algae and weeds in our water.
During this six years we have lubricated the pivot tube once and nothing else. It has done a fabulous job of getting rid of the algae and weeds. We can now see right down to the bottom of the pond and the water is so clear its like an aquarium we can even see the fish swimming in the water.
This windmill aeration has done a great job and we are very happy that we chose a Koenders Windmill Aeration System.

Keeping Our Trout Healthy and Alive For Decades!!!
We have been using Koenders Windmills to aerate our surrounding trout lakes for almost 30 years. We have several lakes in the Kyle area of Saskatchewan, Canada and fishing is a favorite past time of many of the folks in our region.
These windmill aerators have kept our trout healthy and strong during the both the cold winter months and hot summers. During this time we have never had a fish kill. Our winters are severe up here in the prairies of Canada and the summers can get really hot, these windmills are truly built for all seasons. We are just replacing two of the first generation windmill aeration systems that we had installed 29 years ago with one of the Koenders Dual Diaphragm windmill aeration systems, this will go on one of our oldest lakes.
This year we have seen some really nice trout come out of these lakes!!!

KEEPS OUR SPRAYER NOZZELS FROM GETTING CLOGGED UP WITH ALGAE and WEEDS
The Koenders HD 250 Electric Aeration System works really well to keep our sprayer nozzles from getting clogged up with algae, we are very happy with it. This saves us time and money.
We have also noticed that there is a lot less mosquitos in our yard as a result of using the Koender HD 250 aeration system in our pond.

Best Water Quality We Ever Had!!
We purchased the Koenders HD250 Electric Aeration System and it works great. As a result of using It we now have the best water quality we have ever had! The odor from the pond has also been significantly reduced.
We are very happy with it. It keeps a large area of our pond open during the winter to vent off any gases that would usually have been trapped by the ice. This would then come in through the water in our house and make our house smell of rotten eggs at time. I would recommend this “bottom up” aeration system to anyone!

Cranberry Farmer Uses Koenders Windmill Aeration Systems for Almost 20Yrs Maintenance FREE!
I am a cranberry producer in Wisconsin and we have been very impressed with the results from our Koenders aeration windmill, it has done everything we had hoped it would. It has kept the green algae down, which had been a problem due to the high phosphorus run off that gets into our irrigation water from neighbours farms. Subsequently, I have the amount of times I have to clean the section screens has been significantly reduced. Our Koenders’ aeration windmill has also done a great job l in keeping areas of our irrigation pond open during the winter months, getting access to this water in the winter is essential to keep the cranberrys alive and healthy.
We have had our Koenders Aeration windmill for 18yrs now and today was the first time I have had to do any maintenance to it; a simple change of the diaphragm and check valves.

Koenders keep our 6 Million Fish Healthy each Year!!
Roeseler Fish Farms since 1989
Each year we grow and harvest approximately 6 million fish ranging is size and type; blue gill, bass, channel cat, 3 kinds of trout, and perch. To keep these fish healthy and alive we use aerations systems on our 30 or so ponds – aeration systems include various kinds of electric and windmill aeration systems.
Of them we have been using a Koenders Electric Aerator since the mid 90s that just won’t quit. We also have about 15 of Koenders Windmill Aeration systems. Of yours vs the competitors Koenders wins by far. Its cost, reliability and performance has been far superior. Koenders has really thought things through with the windmill aeration systems having an adjustable piston to ensure the compressions are optimized and the engineered design of the compressor. You can really tell that your company is the innovators of windmill aeration systems.

Another Windmill on Lac Sinclair
The windmill has been working very well – we installed it in the summer to help reduce the sludge on our beach area at the cottage. Another one of the cottagers on the lake have done the same thing with successful results so we have decided to do the same thing. Electricity is expensive at the cottage so we decided to use Koenders windmill to aerate the water instead of an electric aeration system.

Koenders Windmill Aeration is Keeping Our House Water Clean!!
We have a single diaphragm windmill with two diffusers controlling the algae in our pond. It has worked wonderfully over the years. We pump water out of the pond into a holding tank for house use. Recently with the high heat the water in the holding tanks has started to smell and would cause itching when it touched skin. We called Koenders to get some recommendations and they advised the water in the holding tank may be too oxygen deprived, allowing bad bacteria to take over. At their recommendation we moved one of the ponds diffusers to the water tank and in a matter of days the smell went away and the water quality improved.

Koenders Windmill Aeration System Does What its Supposed to DO!!!
Our Koenders aeration windmill is working great to keep our water healthy, doing the job it’s supposed to do. We have 2 air diffusers connected to our windmill. After installing our Koenders windmills I would say the water quality and clarity has increased a minimum of 50%. We can really see the bottom of the pond now.
We are very happy with it, not only does it work great to keep our pond healthy and the fish in it, it also looks great, we got our windmill powder coat painted to look like a Black Eyed Susan flower.
Koenders Windmills – Saves My Fish from Winter KILL
The Koenders windmill was a great purchase, you guys have a great product, low maintenance, in fact I didn’t have to even change the diaphragm and check check valves on my windmill aerations system until my 12th year of owning it. It costs practically nothing to maintain. I am a snow bird now and last winter when I went away in December ,(the pond was frozen, it was a very cold winter, thick ice) and when I came back 3 of my neighbours had major fish kills, one of them lost all of his fish (spring fed ponds). I am so glad I got one of your aeration windmills, I didn’t lose a single fish!!
I have really high trees around the pond where the windmill is, I don’t even feel a breeze but the windmill sure is spinning. If you ever need a reference, have them call me.
We Love our Windmill and great Customer Service!!
Hey, I enjoyed talking with you today. I am going to forward you some pictures of our windmill. As I said, WE LOVE OUR WINDMILL. Our water is clearer and our fish seem livelier and our ducks seem to like it too. Everyone we have had contact with at Koenders has been extremely courteous, friendly and knowledgeable and it is a true pleasure doing business with y’all. Y’all have always been very prompt almost within minutes, answering my emails and phone calls. I look forward to many years of business.

Very Pleased With our Koenders Windmills!!!!
“We are just very pleased with our Koenders Windmill Aeration system, very pleased! We didn’t realize how much wind we had until we got our Koenders windmill, the slightest breeze the windmill is aerating. The water has cleared up, the fish are happy; we are catching bigger fish.
I was sceptical on the windmills when I was reading the testimonials, as they were all from the North, but it works great here in the South, we are amazed how well it works. If you have anyone in the South that would like to come see it, we would be happy to show them.”
One Windmill Aerating TWO Ponds!!
“I love my Koenders Windmill, it works great. It definitely keeps the water cleaner. I have one Koenders aeration windmill that I put in between 2 of my ponds and it does a great job of aerating them both. One pond is an acre and a half and the other is a half acre pond. Beyond keeping the water clean, my fish are healthier and bigger. In the winter it also keeps a 30ft diameter hole in my ice covered pond, allowing the sun-rays to get it in, water movement, which improves the overall health of the pond.
I told my wife I want to get another Koenders windmill, my wife said I am doing find with the one I have. I am going to get another one anyway, they work great.”
I have to tell you that we believe your windmill has helped the health of our pond tremendously. We’ve had it for about 6 years and only recently had to replace the diaphragm. We really enjoy our pond now and go swimming in it almost every day during the Summer.

Koenders Windmill Aeration Systems Help Grow BIG and HEALTHY FISH!!!
Our Koenders windmills is working really well, no complaints. In fact, our bottom up aeration system from Koenders are growing these fish to be so big and healthy that just the other day one of our friends were fishing at the pond and the blue gill fish they caught was so big it almost pulled them in the pond. So I would say the windmill aeration system is working well, especially when a Blue Gill fish can do that, ha ha!.
Koenders Water Solutions Inc
We have been using a Koenders Windmill to aerate our 1/2 acre pond for over 15 years. We raise 200-300 gold fish per/yr and my sons sell them to customers and make a little school money. Its amazing how little wind this windmill needs in order to get the bubbles going in our pond. You don’t have to live in a windy city for these units to work well, we live in a relatively low wind area but even despite this our windmill has worked extremely well to keep our pond nice. In addition we have never had a fish kill since installing our windmill aeration system.
Please feel free to share our story with other pond owners.

Our Koenders Windmill Went Up Like A Dream!!
Eight years ago we purchased our 20 acre parcel of land that had a 1 acre pond on it. The pond has a nice beach at one end and is used for fishing and swimming. We stock the pond every year with plenty of perch, bluegill, bass and catfish. After doing some research on-line we learned that in order to keep our pond healthy and clean and avoid fish kill we would need to aerate it. We also learned that bottom up aeration was the most effective way to transfer oxygen to the water. We fell in love with the idea of having a windmill in the back of our property aerating the pond and so we purchased one of your Koenders Windmill Aeration Systems.
We powder coated the windmill a Grass Green (John Deere Green) and it turned out fabulously. The windmill has been virtually maintenance free for over 7 years now and the paint and everything looks outstanding – still looks brand new!!
I must admit I was a little concerned about assembly when we first purchased the windmill for I am a small woman and only weigh about 120 lbs, with no experience working with mechanical equipment. With the help of my sister and mother we put this windmill together and erected it, thing went up like a dream!!!
Love your product!!
Government of Manitoba Using Windmill Aeration on Sewage Lagoons
We installed 2 of your Koenders Windmill Aeration Systems over 10 years ago on 2 of our 3 sewage lagoons up in Thompson MB. Five years ago we installed a 3rd windmill aeration system for our #3 settling pond. These aeration systems have done an amazing job in speeding up the decomposition of organic matter coming into our primary and secondary lagoons.
They aerate these ponds all year round during the freezing cold winters and extremely hot summers and the only maintenance that we have done on them is change out the maintenance kits which we were told is typical every 5-7 years. These units have been a huge assistance to us in managing these lagoons at a time when more and more people are moving into the area. Higher populations are putting larger demands on the sewage lagoons and these aeration systems have assisted us to keep up with these increased load demands.
Manitoba Conservation Group
Our Koenders Windmill Aeration System has done a wonderful job of aerating our 2 acre recreational pond for the last 12-15 years. Until recently, we have never done a thing to this windmill, It has kept the pond water clean and the fish healthy ever since we installed it. We have 10 lb bass in our pond along with Catfish and Bluegills.
Our children grew up playing and fishing in this pond and now our grandkids are doing the same. This past weekend, my 3 year old grand daughter caught a catfish (with a little help). Our family loves fishing and hunting and this pond has been a huge source of enjoyment over the years. Thanks Koenders Water Solutions for a great product!!
I bought a windmill from you over 20 years ago (I think 22) to aerate a dugout on the property for raising trout. It was used for about 5 years and has sat abandoned on the hill all these years. We had a huge pond dug 3 years ago with an island and a 30 foot bridge to the island. This year I decided to once again raise fingerlings and just finished moving the windmill to its new home. Other than lubricating the pivot, it was up and running in no time. A testament to the quality and durability of your product! I’ve included a photo of it for you. The metal is a bit duller than new but I think they call that patina these days.

Our Koenders El2 Still going strong!!
Back in 2011 we wrote a note to Koenders explaining how well our El2 has been doing. We installed it in the early 1990’s and in 2002 we changed the belt and a maintenance repair kit. In 2011 we replaced a maintenance repair kit and now in 2014 we are replacing a maintenance repair kit. This product is incredible – it continues to aerate our 1/2 acre trout and swimming pond.
I understand Koenders has the replacement for the EL2 coming out – the HD 250. I will be happy to buy one of those units if my EL2 ever gives up on me. Koenders has certainly proven its brand worthiness.
Thanks and look forward to our continued success with your products.

No problems with My Windmill EVER!!
We installed our Koenders Windmill Aeration system in 2002 and it has been aerating our 1 acre fish pond ever since. We have Gray Channel Cat Fish, Bass, Blue Gill and Red Ear. Since installing our aerator we have never done anything to it except for greasing the pivot tube on an annual basis so that the windmill can swivel in and out of the wind freely.
During the colder months of the year the windmill keeps the pond 90% open most of the winter ensuring that our fish stay healthy all year round, we have never had a fish kill since our windmill has been up. We now have swans who annually come into the pond during the fall season.
Thanks Koenders Windmills,
My wife and I were just discussing how long our Koenders Windmill has been up and running, it’s been between 10-12 years. The windmill has done a fine job of keeping our pond clean and fish alive. Around here people pay big dollars for pond care specialists to help them keep their ponds clean. I tell everyone to get an Koenders Windmill Aeration System and that will be the first step in a maintenance free pond.
One time I tried a harsh chemical to treat my water (copper sulphate), it killed everything in my pond including all my fish, never again! That stuff may have worked in the 1950’s but not anymore. Its nice to see that companies like Koenders are taking a lead role in manufacturing Natural Pond Treatments that work with aeration systems.
Thanks for great products,

We installed our Koenders Windmill Aeration System over 15 years ago. We are pretty impressed with its performance. Other than having to change out the diaphragm and check valves every 5 years we have not done any other maintenance to it. We use our 1/3rd of an acre pond to fish and swim in. Our windmill aeration system keeps our pond nice and clean.
Koenders Water Solutions Inc,
Since I put my Koenders Windmill Aeration System in 6 years ago the difference in my pond water is night and day. I love my Koenders Windmill.
Koenders Water Solutions,
We have owned our Koenders Windmill Aeration system for over 10 years and until recently have not had to do one thing to it. We just love the the quality of your product and it has done a fabulous job in keeping our pond water healthy and clean.

8 Years and No Maintenance!!
I have three Koenders windmill aeration systems, each one aerating a different fish pond. Each pond is about 3/4 acre in size. My neighbor also has your windmills, he has 2 of them installed on his fish ponds. Ever since we installed these units on our ponds we have never had fish kill offs, we have also never had to do any maintenance on these windmill aeration systems.
We each installed the 12 ft Tower units and even in low winds these windmills turn and provide oxygen to our water. During the winter months they have done a perfect job in keeping an area of the ponds open. My fish ponds have crappie, bass, pike, perch, cat fish and who knows what else. I have caught out of my ponds, what I consider, trophy fish, even a 10 lb cat fish. So keeping the water healthy and clean is very important to us. We appreciate the reliability of your product and the fact that we have not spent any money on electricity to aerate the water or done any maintenance for all this time is amazing. We have saved thousands of dollars with these units.

Click for Larger ImageI have been reading on your website about putting isopropyl alcohol in the anti-icing device. Do I need to keep alcohol in that tank at all times (no just during the freezing months of the year). We purchased this property about 20 months ago and I have rebuilt the pump, replaced the air hose and added an airstone to the system and treated the pond with pond conditioner. I have just recently been reading about the alcohol in the tank. Is that important? I have seen such an improvement in the pond since doing all the repairs and treating it with Natures Pond Conditioner. This system is about 20+ years old and doesn’t look like it has had much maintenance to it but is working very well. Thank you Koenders!!

Recommend a Koenders Windmill Aerator to ANYONE!!
Hi, I purchased a Koenders aerator windmill in 2006 for a 1/3 acre pond here close to Houston. I erected it and put it into use. It has worked perfectly for all these years. I used to have a problem with algae and especially pondweed but this aerator has been a lifesaver. I have not had any fish kills, and the algae is under control – I also add colorant to the pond. Fish are very healthy and I have many large catfish and many small perch in the pond even though the depth is only about 5-6 feet in the middle.
I would definitely recommend a Koenders windmill aerator to anyone who has a pond in order to keep it healthy.

Done Nothing to Our Windmill For 15 Years!!!
Our windmill has been aerating our 1/4 acre pond for over 15 years and it has been pretty well care free for this whole time.
We swim and fish in our pond and the windmill aeration system has done a marvelous job of keeping the water clean.
We used to skate on the pond during the winters but now we aerate all year round and it works great during the freezing weather too.
Customer Service – Koenders Windmills,
I purchased a 16’ windmill over the July 4th weekend and it’s been up and running for about 3 weeks now. I was really impressed how well engineered it was and how everything fit and went together. I opted to anchor the corners by setting poles in concrete and attaching the windmill to that, giving it a really solid base.
So far I’m really impressed , happy and satisfied with your product. I’m looking forward to many years of reliable service from it.
We have owned one of your windmill aeration systems for over 16 years and it has done a marvelous job of keeping our pond water clean and algae free. My husband, Bill, passed away a few years ago but he really enjoyed the pond. That was his thing! I only realized recently that the windmill was good for fish as well as making sure there is no algae in the water.
Really like the look of your windmill and the fact that it does a reliable job of keeping our water clean is a bonus!!
Koenders Water Solutions,
WORKS GREAT!!! NEVER HAD A PROBLEM!!!
We installed our Koenders Windmill in 2006 – it is used to aerate our 3/4 acre pond that is about 11 FT deep. Our pond is stocked with Bass, Blue Gill and Perch. The windmill has kept the fish healthy and alive during all seasons of the year, it also helps keep our pond water clean. We like to swim in the water on occasion so its nice to be able to do that. Thanks again, your product works great and we have never had a problem with it during all these years!
So Impressed with Performance We Ordered 3 More!!
We have been using a Koenders Windmill for over 7 years to aerate one of our settling ponds for compost. It has worked extremely well in eliminating the odors from the water and we have been so impressed with the results that we ordered 3 more Koenders Windmill aeration systems for our other 3 ponds.
Dear Koenders Water Solutions,
Love your Fountains!
Click for Larger ImageI have to tell you we just love the fountain and the light kit. People are in awe of the light show at night coming from our pond. The fountain is so eye catching and relaxing to watch and listen to. Not to mention it’s a conversational piece. We are so glad we added it to our windmill system. By the way the windmill is great too and those hinges make raising and lowering the windmill a snap.
Here are some pictures of our pond with the windmill. We put it up in 2002 after we experienced a significant fish die off in the spring. Since putting it up, our fish are very happy. You’ll notice that we also installed the hinges on it so maintenaince is very easy.
I am looking forward to your Pond Conditioner to see how it works. You may use these pictures in your advertising. The pond is located in Hartland Michigan. Please let me know if there are any other questions.
