Popular Product Questions

First, figure out the surface area of your pond. Next, figure out the depth of your pond and use the estimation guide below to determine how much NPC you need.

Nature’s Pond Conditioner is easy to apply. For aerated ponds, pour bottle contents near aeration bubbles. For un-aerated ponds, dilute in a ratio of 10 gallons of water to 1 gallon of concentrate and pour it throughout your pond.

Nature’s Pond Conditioner Spring/Summer Blend works in water temperature above 15°C/60°F

Fall/Winter blend contains a bacteria protector to be more effective in cooler water. It works in water temperature around 10°C/50°F

Nature’s Pond Conditioner is an All-In-One product, which means you can easily care for your pond with ONE solution. Our concentrated and proprietary blend of beneficial bacteria, enzymes and plant extracts aggressively break up and consume the sludge, organic runoff and debris along your shoreline and at the bottom of your pond, while our food-grade dye enhances the color of your water.

  1. A food-grade dye enhances natural water color
  2. Aerobic bacteria and enzymes consume excess nutrients like phosphorus and nitrogen which helps keep your pond clean and clear
  3. Anaerobic bacteria work to consume pond sludge and muck (up to 12 inches a year!)

While NPC works without aeration, it requires much more frequent application and is not as effective. The additional oxygen that aeration provides creates an optimal environment for NPC to work efficiently.

Yes! NPC is made of all-natural ingredients and will not harm fish, livestock or humans.

Assuming an adequate amount of treatment was added, you should see results in approximately two weeks. This will depend on the pond nutrient load and amount of oxygen in the water.

Depending on the inflow and outflow frequency of the water, Nature’s Pond Conditioner can still be used but the number of treatments might have to be increased.

Sludge and muck is often the main cause of strong pond odor. NPC will help reduce strong odors by decreasing the build up of sludge and muck in your pond.

Yes! Even though we do not condone this practice, NPC will consume the organic matter that you have killed off and has sunk to the bottom of your pond. The most sustainable practice is to remove the unwanted aquatic vegetation with a Cutter N’ Rake.

Algae and weeds are the result of nutrient pollution entering the water; agricultural fertilizer, sewage run-off, grass clippings, bird, fish, and animal waste, and fossil fuels.

Our Nature’s Pond Care products combat the problem of nutrient pollution naturally!

There are many reasons a pond can become depleted of oxygen. The best way to restore and sustain a body of water’s oxygen levels is through AERATION. Adequate levels of oxygen are required to support life within the pond ecosystem. Fish need oxygen the same way we do, and the main cause of fish kill in ponds is due to a lack of oxygen. Bacteria also need oxygen and play a key role in breaking down organic matter to reduce muck and sludge from building up on the bottom of a pond.

Bottom up aeration is the most efficient way to aerate ponds and is up to ten times more effective than surface aeration.

The Koenders Free Air Windmill has a top mounted compressor driven by wind which pushes air through the airline to the bottom of your pond.

You can use our Windmill with up to 1000′ of airline, or you can use our Electric Aerator with up to 1000′ of airline, provided you have access to electricity in the area you wish to place the Electric Aerator.

You can expect your Koenders Windmill or Electric Aerator to provide 10 to 15 years of faithful service. We have customers who are still using equipment purchased in 1988.

Yes. We have extension packages available. Contact a Dealer near you or be in touch with us.

You can either tie it down using weights or purchase the Koenders Weighted Airline.

Under normal use, you can expect your Airstone Diffuser to last a lifetime. It may require a cleaning every two years or so, depending upon water conditions.

The manual can be found inside of the compressor box and the bolt package for the 0 to 8 ft tower section is in the blade and tail box.

Check major components yearly to ensure there is no damage.

Freezing can damage or cause wear and tear. If you are in a colder climate, we recommend attaching the Koenders Freeze Control Unit. When it’s cold and you compress air, condensation can form in the airline and can create an ice blockage. With a freeze control unit, alcohol will be injected to melt the ice. This will help ensure aeration during winter as well as help protect the compressor from back pressure due to blockages. It is recommended that Isopropyl Alcohol at 90 to 99% purity be used. (Purchase here)

It is recommended to do an air intake filter replacement twice a year. Depending on the model, the air intake filter will be located on the outside of the unit, or on the inside attached to the motor. Replacing the filter ensures maximum airflow and helps protect the motor from debris and dust. (Purchase here)

In rare climate and aeration combinations, ice will build up rapidly in the airline, causing the HD Freeze Kit to operate too frequently. In those situations, a Bleed-Off Valve should be installed to reduce the airflow. Full aeration can resume in the spring. Please call 1-877-888-7707 to order.

The hard-plastic airline is the regular airline that is connected to the compressor. The optional thick rubber airline is a weighted airline, which settles on and contours to the bottom of the pond, helping remove condensation.

It is recommended that the Airstone be installed in a plastic pail to reduce it stirring up the pond or dugout mud as well as to help keep debris off the Airstone. It is also recommended that you run a nylon rope through two slides of the pail, not the handle, so that you can retrieve it at any time. (Purchase here)

Fountains, or Surface Aeration, pump water into the air, creating small droplets that collect oxygen from the atmosphere, and fall back into the water. This helps control top level algae and weeds, but does not aerate the bottom of the pond, where oxygen is needed most. The bottom of a pond is where dead organic matter such as weeds, algae, and other nutrient waste sink down and decay. If there is no oxygen at the bottom of the pond to support the bacteria breaking down waste, a build up of muck and sludge will occur, requiring costly dredging to remove.

Bottom up Aeration systems are 5 to 10 times more effective than surface aeration; providing total pond aeration from bottom up to the top no matter how deep the water.

Bacteria are microscopic living organisms found in all matter. Some are beneficial, some are not. The bacteria that have been tested and proven in our Nature’s Pond blend are beneficial in the decomposition process of organic matter found in ponds and lakes. NOTE: Not all blends of bacteria are created equal! Our blend of both anaerobic (extremely low oxygen levels required) and aerobic (requiring oxygen) bacteria have been proven to work and field tested in tens of thousands of ponds in all regions and climates across the world.

Bacteria replicate at different rates depending on the type of bacteria and the environment they are in. Bacteria are essentially enzyme makers; as they consume various kinds of organic matter and different forms of waste, they excrete enzymes. They also convert consumed organic matter into non-toxic by-products such as C02 (carbon dioxide) and H20 (water), leaving no toxic residue in the process.

Nature’s Pond Conditioner’s blends of bacteria are 100% natural, safe, and non-pathogenic. They consume the muck and sludge at the bottom of the ponds, lakes as well as the suspended nutrients in the water resulting in healthy, clean and clear water.

Enzymes are NOT living organisms, they are biological molecules (typically in the form of proteins) that help speed up almost all chemical reactions. Some enzymes help bind molecules to make new ones, others break down larger molecules to help in the digestion process or decomposition process.

Having the right enzyme mix already present in any formulation can dramatically speed up the decomposition process of organic matter. Unlike bacteria, enzymes cannot reproduce themselves and they do not actually consume waste. They are, however, essential in breaking down organic waste so that bacteria can consume it.

Nature’s Pond Conditioner has a formulation of enzymes to ensure the beneficial bacteria has a readily available food source for its never ending appetite for organic waste.

Nature’s Pond Conditioner contains a natural blend of beneficial bacteria and enzymes.

Chemicals are not living organisms, they are substances that are either liquid, solid, or gas. The chemicals we want to avoid in our ponds, lakes and waterways, come in the form of detergents, pesticides, algaecides, corrosive acids and metals.

Chemicals cannot reproduce themselves and have a one-time impact with immediate and sometimes detrimental effects. Pond chemicals are promoted as magical remedies for pond care problems. Chemicals are short lived, not sustainable, and environmentally harmful.

Harsh and dangerous chemicals are promoted to reduce sludge and muck, but chemical use increases health risks to the users, water, environment and wildlife. There are less toxic chemicals that are promoted the same way, but they are not as effective at oxidizing the sludge and muck as natural bacteria and enzymes.

Other harsh chemicals leave toxic residue behind, which has harmful impacts on water and everything in it or that comes in contact with it such as crops, livestock, and wildlife.
