[Suboc]

Any one have an idea what kind of algae im combatting here? it sprung up in the past week. from no algae to POW almost totally cotton covered rocks. its also only growing on my back glass and the marco rock i put in the tank all my seed rocks have none. It also seems nothing will eat it.

Im guessing its an algae. My yellow tang eats everything that grows (including turf algae.
