My fish kill happened last year because my aerator was not working during the hottest two weeks of the year, that is when all my fish went belly up. Also, I think the depth of the pond should be OK. At full capacity it sets around 16 feet in the middle. Presently I think it is around 12+ feet. Last year it got down to about 10 feet by mid August. I feel pretty good about restocking and letting the aerator get me through the year this coming summer.
