3/4 acre pond, 9’ deep, western N.Y.
Had a bad fish kill a couple years ago, was advised that my aerator was too deep (7’). So now I have it set at 4’ for the winter and run it about 25 minutes a day.
Had about 40 fish dead this week, also have some that are beaching themselves, gasping for oxygen, but just a few of those so far.
Did I not run the aerator long enough, too much?
The ice has only been off for a couple days, should I run the aerator more or?
