Well after 4 years I finally had a fish kill but don't know why. My pond is about 1/2 acre, 17 ft deep in the middle, about 30 years old, BG, BCP, and LMB. I stocked 25 LMB 3 years ago due to not catching any and having a LOT of BG. I have been stocking TP the previous three years but have not this year. I do have a lot of FA and Chara.

I'm trying to figure out why this happened. I do aerate from around midnight to 8am. We have had a lot of rain this spring and the pond has been going over the emergency spillway. Recent rains have knocked down the FA. Could that have caused a DO crash even with the aerator running?

Tonight I scooped out around 100 BG all sizes, 2 small LMB and 7 2-3 lb LMB. There are about 20 - 30 more BG that I couldn't get to. Should I turn on the Aerator 24/7?

Well I decided to go ahead and turn the aerator back on. I figure it couldn't hurt.

Thanks.
