BBA is supposedly harmless right? I did have a problem with allot of regular hair algae before I set the lights on a timer but since then it's calmed down and there is allot of floating plants in there at the moment so the light that does get down there Is pretty filtered, I'ma leave it and take photos every day for a week to see how it develops, it doesn't seem the be hair like structure's at least not yet
