Koenders aeration systems have been keeping our Retention pond clean for 10 years. We have done nothing on it until recently when we replaced the maintenance repair kit.

The water comes off the buildings and large parking lots through ditches gathering into the retention area near the building. We originally installed the aeration system to ensure the pond does not stagnate. We wanted to eliminate odors and breeding of mosquitoes especially now due to the risk of west nile virus. We are extremely happy with our Koenders aeration system.

I love my Koenders Windmill

We bought a Koenders Windmill last year and truly love it. It was easy to install, taking two of us about a day to assemble and set up the diffusers in the pond. Our pond used to be covered with filamentous algae throughout the summer months. Ever since we installed the windmill aeration system - we no longer have any issues.

It is keeping our pond and fish healthy and alive. The pond is 8 Ft deep
and we can now see right down to the bottom of the pond. I am extremely proud of my pond and the super great product from Koenders Windmills.

I will be installing another Koenders WIndmill on our other 5 acre pond to keep our fish alive this winter. We had a major fish kill last year and do not want this same thing to happen again this winter.
