To make this short and sweet, I've got a 100 gallon that houses a snowflake moray, a 29 gallon with two clown fish and an assortment of polyps and coral, and a 55 gallon sump. All three share the same water as they are all tied into the same system. All my parameters are at zero, but i'm having a problem with red hair algae in my 29 gallon coral/clown tank. I don't want to damage my polyps by physically removing the algae, does anyone know a better way? Ie cleanup crew etc.?
