Koenders Windmills

Pond Aeration

Koenders Windmills is a long term, low maintenance way to aerate your pond in all four seasons. Koenders Windmills produce the results of an electric bubbler without the need for electricity. Windmills are available in 12’, 16’ and 20’ heights and should be installed where they will catch the most wind.  A 10′ deep pond with a good wind can move 250 GPM.  Windmill pond aeration will de-gas a pond reducing carbon dioxide, nitrates, sulfur and other unwanted gases.  As a result, the natural decomposition will speed up of the organic material, creating more good bacteria to consume partials and bottom sludge. 

Reducing weeds and algae

Aquatic weeds and filamentous algae thrive from carbon dioxide and other gases, so degassing will result in a reduction of aquatic weeds. Additionally, a decrease of gasses at the pond bottom will reduce pond sulfur and unwanted smells.

Winter oxygen needs

To prevent winter fish kill in the winter, oxygen is required to get rid of carbon dioxide. The gas transfer occurs when the oxygen leaves the air diffuser on its way to the surface, keeping a hole open where the gases will escape. This gas transfer process is also used to let water fowl have open water in the winter.
