Anyone?

Can anyone tell me what this is? I have two or three patches in my tank… Tanks two years old and fairly stable and these are patches that the tangs do not seem to eat ? It’s hard to tell in the pictures but it’s dark green and it looks like it has teeny little bubbles on it

Look like green cyanobacteria!

+1 for green cyno bacteria

Dr. Tim cyano recipe will take care of that. Marine depot just posted a video on this...
