I have this algae in my pond this year(see pics). Haven't had it before. I think it's FA. Not sure though. I've recently stocked the pond with more fish and started feeding. Would that have caused this stuff to start growing? I had cattails and pond weed last year. Imazipir knocked out the excess cattails. Adding grass carp and pond colorant has taken care of most of the pondweed. My pond is filled by a well almost no run off. So,it gets really clear if I don't color it. But now this stuff popped up. Some of it is submerged and looks like big clouds of green cotton candy under the surface. When it reaches the surface it turns dark and seems to bubble. What is it and how do I get rid of it? What am I doing that caused this? Thanks for any help you can offer.
