Pond is about 3/4 acre and about 8' in places. I think it had a heavy fish load and I do feed 3 sec twice a day sometimes more if I'm out there and just want to see fish. Pond has always been healthy and fishing great. It's about 5 years old and never a problem except treating fa with copper sulfate and killin some cc a while back. 10"+ cnbg, 5lb+ lmb, and some really large cc. I use some beneficial bacteria to help with over fertilization "pond clear" & "Eco boost" since I mow and have horse pasture run off. I also use that blue dye, the name slips me. I have been doing the same this whole time and no probs. Had to be the major restart of the aerator and stratification.
