I am having an algae problem in one of my tanks. It appears to be a hair algae that is very dark in color. It likes to grow on the tops of the plants, the tank is 20gal its been setup for over a year. 2wpg of light and pressurised co2. Below is a bad pic of the algae, but the best I could get. What would be the best way to try to get rid of it?
