In my old pond, there were never any water weeds other than FA, and never much of that. There was something on the bottom that came up when the pond turned over, and that happened only once or twice in nine yr. The pond was seldom if ever clear. I could generally see objects down a foot to a foot and a half. After a heavy rain it would get muddy and stay that way for a few days. My new pond is very clear. Even after heavy rain, it doesn't really get muddy, only cloudy, and clears up quickly.
