thanks for posting this donnie, and very sorry to hear this news.
i'm with shawn wanting to know some specifics about yer pond size so i can learn more about my situation.
i have a shrinking pond due to hot dry CA summer conditions and no supplemental water. it goes from about 1 acre full max depth 15 ft in spring, to probably 1/2 to 2/3 acre, max depth 8 to 9 foot by fall. the pond contains alot of fish now. i definitely face potential problems with decreasing water, increasing biomass. i aerate with two bottom diffusors from 1130 at night to 0730 in the morning. so far so good.
