This stuff showed up about two weeks ago, and was a light green. Thinking it was algae, I sprayed it with Cutrine and it turned a rusty red within a few minutes. But, it's still here...it disappears with the rain, and reforms the next day like FA will.
I have been keeping the pond darker than usual with aquashade, but I'm not sure if this is decomposing FA or another variety that has moved in to take advantage of the FA's greatly reduced presence. It sits right at the surface, and will move with the slightest breeze. It seems to be comprised of foam mostly, but it will leave behind fragments of "film", or skin if disturbed.
