I have constantly been fighting off black brush algae, or black beard, or whatever you call the ugly hair looking grossness that takes over your tank. I have tried different fish, medicines, physical removal and whatever else. Finally I think I have it under control. I have a snail problem though. I think the snails have taken out the ugly algae. 
I don't want to experiment with the algae, but I know it's a whole lot easier to kill snails than it is to rid your aquarium of the algae.
