So I have a breakout of brown algae in my frag tank 48x24x6.5 yes shallow frag tank I know. I have a mp10 on. I started getting it when I went to black egg create. How would you get rid of brown algae. I have done two 15 gallon water changes. I'm thinking about getting chemi-clean (I have SPS and polyps). yes I have a protein skimmer and yes I have carbon and GFO in it and my phosphate is 0.
