water, a good skimmer, and a fuge. All will help remove the nutients are are feeding the algae. I'm going through a hair algae battle on my new (5 months) 125 gallon tank. Not unexpected. The algae has started to slowly diminish, I've just got to wait it out. If you want a fish to eat the stuff, get a foxface if your tank is big enough. I got one a week ago, not to eat the algae, but because I like the look of them. Well, he's mowing down the algae, so that's a good side benefit. I'm still doing my best to make sure the algae doesn't have the nutriants to grow.
