TyW33, good point on the things being anaerobic down in the mud, makes sense. I'm looking for some of the Pro Lab One Flush to try out. So far I can't find a local dealer. Hey, I see you are also from Minnesota. I was born and raised in Mankato, spent lots of days fishing on Lake Washington, Madison Lake, et. If you have a pond and raise fish it would be interesting to compare notes. I find that our friends down south have a wealth of insight in pond culture but once in a while things are a little different up here where we get 3 feet of ice in the winter and the pond is frozen from November to April.
