When the GSP polyps open during the day, you can't see it. But you can see it with the lights off, and you shine the LED flashlight on my phone. It looks like it's a green, almost fuzzy looking algae. It had clearly killed off some of the GSP where this stuff is at. I can't ID it, I'm not really even sure what it is, but since I first discovered this, it's spread.
Any idea what this might be and how to deal with it?
