I have been fighting green hair algae. I have 0 nitrates and 0 phosphates. I do water changes every two weeks, clean my media regularly, feed every other day once, vacuum my substrate, bulbs are only 7 mnths old, skimmer is collecting alot, good flow but I still am getting green hair algae. It's now growing on my heater, filter intake, and I noticed a small piece on my leather. I think I am in trouble. I am using black diamond carbon, which I clean regularly and change every few weeks. Phosguard and nitrate sponge.
