ID Please

[rdnyva]

Can someone ID this for me and recommend a course of action. It's a pretty crappy picture but you can see the problem on the right side of the coral. Its a tannish gray and looks like snot. It also has air bubbles trapped in it which make it rise and float. I think it may be a flow problem since it is confined (mostly) to a few specific rocks on one side of the tank. Thanks

That's not a good pic, but my first guess would be cyanobacteria although it's typically red.. Check your PO4, cut down on feeding, and try to suck it off with a turkey baster.

On a side note. If those are zoanthids right below the candy cane, they will more than likely end up getting stung.
