So whats this?

[Yellowtang]

It's not cryno doesn't move easy. I brushed it off with a toothbrush
6 hours ago and it came back that fast. Pipe organ coral was looking fine yesterday when lights went out. This morning it didn't come out. I was thinking about a dip but didn't do it yet. These few pollips have survived
just about every known dissaster known to reef tanks and it would torque my jaws to loose these few to whatever this is. To me it looks like a bacteria, plus the speed in which it returns. Suggestions?

Moderators it would probably be better in general reef discusion where I thought I was puting it. Thanks

just looks like algae to me. you could try and dip it. what are your nitrate + phosphate levels?

 

[Yellowtang]

Nitrates 5 and never have tested phosphate level I dont have a algae problem elsewere. Just never seen algae that grows that fast.
