It's called black brush algae and it's a tough one to eliminate - see photo on this link: http://www.floridadriftwood.com/algae_identification.html

Good Answers, the algae is relate to the hair algae that no pleco will touch with a ten foot pole. You need some Siamese alage eaters. They love the stuff and will have it cleaned in a few days. Get a half a dozen or so, they do wonders. Make sure you get the right ones. Do not get the Chinese alage eaters they don't like the stuff either. Good Luck
