I have some sort of white/clear film slime algae mat growing on one of my live rocks but I can't get it to come out on any pictures at least visibly anyway. I first noticed it about two weeks ago and it has grown pretty quickly so now it concerns me but I don't know if its good or bad. I was searching but I couldn't find any good websites showing images of different algae's to help me identify it. As you can see its difficult to describe(white, clear, film, slime, mat) especially without a good picture.:frustrat: Can someone give me a list of good websites to look at it for identification?
