I walked around our pond yesterday and noticed something I haven't seen before. After searching/reading here, investigating some of the vegetation links, and Googling, I'm wondering if this is phytoplankton. If so, is it anything I should be concerned about at this point---since from what I've read, it can be beneficial to have?

It first appeared Monday, and we'd had a thunderstorm Saturday that dumped an inch of rain. I don't have TONS of this bright green stuff, and some of it is very definitely suspended in the water. Where it's bunched up on the shoreline, I can't pick it up...it simply breaks up when I try.

Overall, the pond looks good right now until you look close up at this stuff. What are your thoughts? THANKS for any/all input!

One other thing... even though I think this this article may be talking more about commercial catfish ponds, the information was interesting. Do you experts agree with it?
