Does anybody have an idea on how I can get rid of hair algae. I have tested my water over and over with all known tests and all is fine. I use phosguard in my sump. I have 4 green crabs, 4 pepermint shrimp, over a hundred snails, over 150 hermits, worms ect. in a 150 Reef. I don't want to break down the tank. Any help? :roll:
