Impossible to say for certain by gross appearance. Is this in a frag tank? How old is the tank? What are the PO4 and NO3 levels.

Microscope views are the only way to be certain.

Cyano is typically deep red. Most likely diatoms IMO. If this is a new tank even more likely to be diatoms.

Yes the tank is about 3 months old no3 is 10ppm and po4 is .1 ppm
