hey, all. hair algae is attacking my javas! its not so bad on the ferns, because the pleco usually just eats it off. its the moss I worry about. it's all over some strands. how do I control it? I can't just scrape it off by hand, and the pleco can't eat it off without eating the moss itself, which she actually does in high volume. sooo.... would a blackout take care of it? are there any types of shrimp that eat it? normally I wouldn't care, but it seems to be killing off my moss. help me!
