Hi! I lost all my 35 fish this past winter.I drain the 800 gal pond.I was
surprised to see that much dirt at the bottom.I say clean the pond out every
second year.Keep the pump one foot or more from the bottom.
E-mail me if you want.Everything is Ok now.I have to clean my filter every
second week.I have about 20 new fish and they are doing fine
