Hi Greg, I was going to call you today about my pond. It sounds exactly like what Ric described, and looks like the pictures that WS posted. I don't fertilize (have constant water flowing into and out of pond). Visibility is about 6". It's not muddy brown like it was after all of the rain in early June, but hasn't been clear for a month+. Do I need to hit it with Alum & Hyd Lime? Ph is 7.8
