I have an 80g frag tank trigger 39 sump, protein skimmer, calcium reactor, uv, with a few lps, a lot of zoa, and eventually want sps in the tank. The issue I have is with hair algae in the tank. I have 3 clowns and a kole tang in there. I have a few snail and crabs in there now but still have algae in there. What is a good clean up crew for the tank?
