I had an algae outbreak all over my tank. I needed the light on, but it was feeding the algae that way, so I bought several plants and a moss ball. Shortly after that, the algae went away completely. Then I got a snail to control it. Maybe you should try this? It just may work, and if not, then live plants are always good for a tank:)
I either talk to my fish when I'm mad, or I'm mad because I talk to my fish.
