I really need all the help I can get with this one. So I've been fighting this for weeks now and I don't know what to do. I have this gross looking blackish reddish 'algae' on my rocks. I have been doing water changes and I siphoned some of it off with a turkey baster but it keeps coming back and now it is spreading to some of my other rocks. BTW I have a FOWLR. 45G with 2 clowns, 1 serpant star and a bunch of hermit crabs.
