My pond had all of the fish you have, clams, snails, etc, except I had large mouth bass in a one acre pond, plus I had carp, (20 KOI, and 6 Israeli carp) for 10 years until a fish kill. I fed my fish and so I know I had 20 KOI and 6 Israeli carp at the end of the 10 years and no more. I had all 20 of the KOI named as they were like pets. The carp kept my pond FA free. I didn’t feel the turbidity was bad.
