OK, I've been in the saltwater tanks for about 4 or 5 years, I understand quite abit but not all, I have about 90 lbs of live rock that was completely covered in corraline algae, (beautiful) about 3 months ago green algae started growing on it and completely covered alot of the rocks, it's almost "grasslike" short stubby, it's not hair algae, but it's hard to get off, I have done a ton of water changes, great powerheads are in there for circulation, I have a maxi-reef sump, protein skimmer that works great, I don't understand the algae problem, it's taking over, they have fine little bubbles on them from time to time, I brush them off, do I need carbon in my sump, I'm thinking this might be the problem, because I switched from a canister filter that had carbon to the sump, just wondering Please help Mark
