Well, my pond currently has an estimated 210 pounds of stocked fish and better than average amounts of minnows, tadpoles, and crawdads...so I do not beleive it is overburdened with respect to bioload, but it has been muddy most of the winter with 6 to 12 inches of clarity (secchi disk readings), and there is little to no visible vegitation below the waterline. I still think that my aeration system is causing alot of the turbidity, but we have had a fair amount of inlfow too. With all that said I think I will keep the air running 2 hours a day just for peace of mind if nothing else.
