Pond Boss Forums AERATION Systems questions How to aerate a long, thin retention pond system?

I'm sorry to say it, but I agree with Bill's assessment. Sunlight can get to the whole bottom of the BOW, and that means algae and plants can grow everywhere. In a BOW that shallow, oxygen depletion is not an issue during the day. A bottom aeration system isn't that efficient in those water depths - I'd look into agitators or fountains to help put some water movement into the pond.

Aeration isn't the magic bullet you are looking for. If you can reduce the majority of nutrients in the pond, that will help a lot. Aluminum sulfate treatment, etc. I don't know if Tilapia are legal to stock in Michigan, but if they are, I would add 50 pounds per surface acre as soon as the water temperature got into the mid 60's in the Spring.

If the water was 6'-8' deep, then we're talking a whole new ballgame.
