The first step should be to evaluate your system in the way of nutrients. It sounds like you have Cyanobacteria, Red Slime or Blue Green algae, it grows as a result of phosphate and nitrate (nutrients) in your system. Get a good idea of your current nitrate and phosphate levels, and take the proper steps to eliminate them. Tap water, food, and fish waste are the usual suspects, using RO/DI water, straining food, protein skimmers, GFO and water changes are all ways to help keep nutrients down.

While performing a water change siphon off the Cyano, after that try to keep the nutrients down and you may solve your problem. If it seems that your stuff just grows back after a day or two, a treatment of Red Slime remover may be in order.

Do a couple of searches here and you'll find an abundance of info on it, how to get rid of it, and what to do to ensure that it doesn't come back.

sounds like cyano bacteria, you need to ensure the water added to the tank is totally pure and nutrient free, a ro-di is best for that, also dont overfeed your fish, keep the water moving about by powerheads and also suck as much of the stuff out as possible when you water change next, this is a start, then keep at it.

There is a product called Chemi-Clean by Boyd Industries that works great on getting rid of that stuff. You can find it at most aquarium stores.

Advise against Chemiclean, but DO hope you have a potent skimmer. To kill this stuff, turn out your lights for 3 days once a month, and keep that skimmer working. It's no worse than what happens in the ocean on a cloudy day. Chemiclean will take it out too fast, plus kibosh some of your bacteria, and it's real rough on a tank. The lights-out method works more slowly and a decent skimmer can keep up with it.

I've been battling the stuff in my newest tank for the last few months so I feel your pain. I've got the nutrients down very low, use carbon, GFO and DI, skim like hell and have a RDSB Fuge with a good deal of Macro - it's still there so I just hit it with Chemiclean last night, we'll see how it works. I've only used the red slime removers in the past as a last resort, as you have to turn off the protein skimmer and stop running carbon, so bringing the water quality back up after a few days of treatment is a royal pita.

Good Luck though - hopefully the natural remedies will work for you, seems like I got stuck with a super strand that hangs on for dear life.

Chemi-Clean has been known to nuke tanks, and it's usually a temporary bandage at best. There's likely an underlying nutrient problem and no chemical will solve that.
