Windmill Aeration in Canada

Windmill Aeration can be a valuable tool to aerate your pond, dugout or lake. Windmill aerators have some limitations though. Windmills are a good option if there is no power available, however if power is within even 500 feet of the shoreline, electric aeration is a far more efficient and economical aeration solution.

Electric aeration is the more efficient and reliable option for fish ponds, however windmill and solar aeration are alternatives if power is not within 500'.

Alberta Windmill Aerators

Ackenberry Trout Farm has noticed many ponds with old windmills that have blue-green algae problems. This happens because the pond bottom has become organically active, and the microbes use up oxygen very quickly.


The bottom of the pond goes anaerobic, and phosphates and other nutrients are released at the pond bottom. When your windmill starts up again this nutrient rich water is mixed into the upper layers of your pond.  

Windmill Aerator Sizing

Ackenberry Trout Farm sells Outdoor Water Solutions Windmills both wholesale and retail in Canada. These windmills produce more air than older windmills using a larger blade, larger diaphram and balcam technology. To double the efficiency of these we add two Can-Air SS Diffuser assemblies to replace the airstones.

It is very important to size your windmill needs properly. Please contact our sister company Pond Pro Canada if you want help sizing an aeration system for your pond. 

If the the pond bottom is organic coupled with high BOD values you may require more than one windmill.   Windy areas such as Brooks, Lethbridge, Pincher Creek require less windmills. Other places in Alberta such as Edmonton, or Red Deer require more windmills.

You can improve your windmill performance by adding a more efficient air diffuser than the Manufacturer supplied stone.  Ackenberry Trout Farm sells:
