I have a three year old pond, about 1/4 acre. It's banks are well vegetated, and the drainage area is all mowed lawn. The lawn is not fertilized. The pond is aerated. I am unsure of whether I have a strong bloom, or if the aerator is suspending silt. The airstones are on the bottom, but are on a large rubber pad. There are also many Channel Catfish in the pond, could they be stirring up silt? Secchi disk reading of roughly 18 inches. I know that is acceptable, but I would prefer more clarity. Any help would be greatly appreciated. If it is an algae bloom what is the best way to temper it back. Also the fish are fed daily, so I am certain that the pond is fairly fertile. It also clears somewhat during the winter, which I would expect of a bloom, but the aerator is also turned off then as well.
I would appreciate any and all ideas. Thanks
