This tank belongs to my uncle in which he has had for several years now. However, he neglected his reef for several months up untill my mother and I took over' getting things back slowly into order. Our question is " Is this Cyanobacteria or coraline algae? " it is a pretty red when you put on reef glasses for the blue lights, but brownish with the regular white light on. We have been doing several water changes every week for about 2 months.
