Refugium

[Jcj0033]

Hey guys I recently added a refugium to my 80 gallon saltwater tank and it's been ok for about a month, now the problem is that I have cynobacteria growth in my refugium, should I be concerned, is cynobacteria in te refugium a bad thing, and if so how can I fix the problem

It's fine as long as it's not in the display. I would leave it alone. Anything in the refugium that absorbs nutrients is a good thing.
