Well I guess now is the time to show my complete ignorance. I have a 5 week old 72galBF and I purchased a piece of live rock that has what I have determined from reading the posts here (I just found out about this site) to be hair algae. I am setting up the tank to be for fish and small critters like snails and hermmies. My question is how terrible is this hair algae and what should I do to get rid/eradicate it.
