Pond Boss Forums GENERAL QUESTIONS Muddy water Tried the aluminum sulfate on a 1/2 acre pond.

From experience, I'd guess there is a lack of feeding for 3 reasons...

First, as already thought, the fish are getting used to the tremendous clarity.

Second, the fish are feeding heavily, naturally, again, due to clarity.

Third, some pH shock since a 3:2 ratio of Alum:hydrated lime raised pH quickly instead of being balanced.

As long as the shock didn't kill any, all will be great soon with feeding.

I'll be shocked if clarity lasts...Not due to colloidal clay re-emerging, but due to so many catfish stirring the bottom and keeping things stirred up. The alum will make sediments fall back out quickly, but that many CC in such a small area will move a LOT of sediments around!

Great job!
