Thanks Haplo. Last year the pond was less than an acre by the end of the summer. It gets screaming hot here in the summer with light winds so when the bluegill do there rabbit thing we could have a problem by next year. This year with all the rain it is a 2 ac pond & its holding the water well. I'm aiming for a bass pond here too & I've heard they're the first to go with low DO. Neighbor had a fish kill of cc last year during this time of year but he overstocks I think. I think you are right about testing the DO now though.
