Guys,
I sure do appreciate all the help. I do have a fountain that I use throughout the warmer months, but it sounds like a bottom diffuser is the way to go to burn up the muck. My pond is the shape of an ice rink. Approx. 220 ft long and 90 ft wide. As I have no knowledge of diffusers, exactly what type and size am I looking to buy to handle this size pond. Thanks again to all.
