How many CC do you have stocked? Have you ever done a "jar test" to see if the water clears on it's own when undisturbed? Could be the CC stirring everything up...
Yes, I did a jar test. It did not settle out. Typical NC piedmont area clay pond.
It was turbid prior to stocking.
I think the ag lime helped some.
PH was 5.7 before 1500lbs of ag lime.
It's closer to 7 now.
Pond is .70 acre, 8ft deep with aeration.
It has 75 6" CC, plus last year's 25 CC which are around 12"-14" now.
It also has, what I would consider, a lot of crayfish. No positive ID on the specific type, but I don't think they are the burrowing type.
