Mike, thanks for the reply. I will have to try a couple samples to see what happens. It did cool off quite a bit after that storm last night so I will probably wait a couple weeks before i try to apply anything. In answer to your question the pond is just over a half acre. It is about 7' at its deepest point and averages probably just over 3'. It does have a pretty deep layer of muck too. I'm hoping that over time the aeration will help with that. I'll see how things go as the weather gets warmer.

Eric
