I'm in a little bit of a dilemma. I have a 120 gallon tank, lots of plants, and lots of fish. I have 7 discus in with the fish and was given some beefheart concoction to feed them. they like it, but they didn't eat all of it, so small bits were left around my tank and now i struggle with this white fuzz (looks like fungus) that clings to rocks, plants.... i have upped my water change frequency to try to clean it all up, but it just keeps coming back. my levels are all in check, but i have thius unsightly 'fuzz' at the bottom of the tank. short of tearing my whole tank down, does anyone have any ideas, or suggestions??? thanks, b
