My friend who own a lfs, who went to school for marine biology, is not confident that a refugium is the best thing. On one side it takes out phosphate and nitrate which is great, but one point I've never seen talked about, does it take out a lot of nutrients that help the corals grow. The macro algae grows extremely quick compared to corals. He has tanks that have them and don't have them, his point to me is my parameters are all in a good range why add one. My thoughts of adding one is anything to keep my water as perfect as possible why not? Anyone have any thoughts?
Thanks
