I have a 55 gallon FOWLR tank setup and running now for 1 and a half months. There is 5 damsels (about to be removed), a clown, and a dwarf lion, 15 Astrea Snails, 15 bule legged hermits. All of the sudden I have been having a big brown algae problem and don't know what to do. The subsrate is crushed florida coral with coral life 50/50 lighting (10,000K and Actinic), HOB Seaclone 100 Protien Skimmer, HOB filter about to be 120 gallon canister. I did a water change 2 days ago and still have a terrible problem with the brown algae. Is there anything you could suggest??? The lights are on a 11 day 13 night cycle with a timer. Please let me know ASAP.
