STUDY

3rd party study confirms that Koenders windmills have the best performance ratings in the industry!

Principle behind Aeration

“Aer’ate: “to oxygenate; to purify by exposure to air”
To create an upward current to expose the bottom water to oxygen

Benefits of Aeration

Toxic gases from the bottom (hydrogen sulfide, carbon dioxide and methane) are vented from the water to the atmosphere
Rate of decomposition of fish feces and plant debris is increased 30 fold
Reduces the rate of sedimentation at the pond bottom
Algae causing phosphorous is greatly reduced
Safe – no hazards to boaters or swimmers
Improved fish health, improved water quality, so livestock will drink more
Improved water clarity – better weight gain for livestock, good quality water for household use
Greatly reduces the risk of West Nile Virus

Testimonials

"Our pond brings a great deal of pleasure to me, thus I want to keep it algae and muck free especially in the hot summer months where pond water issues area more predominant. This year we had a very hot summer, extreme temperatures that got up into the high 80’s, low 90’s and with the use of Koender’s Nature’s Pond Conditioner and aeration windmill I was able to keep my pond algae and muck free. My goal has always been to prevent pond water issues from occurring as opposed to waiting until there is an issue."
