Is brown algae something you just have to fight with forever or will it go away eventually. I have a protein skimmer running. My tank is a 29G reef tank with both lps and sps. 3 fish. Tank is a year old. I have a bio wheel penguin hang on the back that i took the bio wheels out of because I read that can cause major algae problems. I just don't know what to do. Lighting is LED. Does really well. Good growth and color on corals. Just wondering why I seem to be in a constant battle with this stuff. Any pointers? Or is this just the life of a reefer
