Im new to reef aquariums and need advice on controlling red algae. I have a 55 gal. with brown polyps,fiji rock, 3 snails, cleaner shrimp, yellow tang and diadem basslet... Protein skimmer, 4 bio wheels & CoralLife power compact flourescent(white light runs 8hrs & blue runs 12hrs)...It is my first saltwater tank. It's been running about a year now and everything has been looking great. My fish and polyps have grown and the shrimp shed it's exoskeleton twice. The last thing I added was Fiji rock(about 8 lbs). I have been using my hands to remove as much red algae i can. It is hard to get it off the polyps. They don't seem to like the algae at all. A few polyps unattached from one of my live rocks and I placed them on another rock. They seem ok. Should I glue them? If so,what glue? I appreciate your time and knowledge.God bless.
