Suspended green particles? That's not any part of a phytoplankton bloom. From your description, I think it's possible that you might have too many fish for the environment.

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.

Boy, if I say "sic em", you'd better look for something to bite. Sam Shelley Rancher and Farmer Muleshoe Texas 1892-1985 RIP
