I am new to saltwater and have two questions. First off I have a 55 gal FOWLR
tank that has been up and running for 3 months and there is a dark slime coating my substrate (40 lbs crushed coral and 20 lbs live sand) Does anybody know what it is and how can I get rid of it. Second I have to clean the glass daily, sometimes twice because of the algae film. I plan on getting more snails, but is that fast of growth normal? The nitrates and phosphates are 0, so I am really confused on what is causing the algae growth. Thanks for any advise that I can get.
