I cannot seem to get rid of this, scrub it/blow it off the rocks, siphon it out and the next day it's back. Actually it seems to settle back out everywhere within an hour of being blown off of the rock.
For what it's worth, yesterday this coral was scrubbed clean with peroxide and a toothbrush.

My guess is there's at least two main organisms there. A lighter filamentous one (green hair algae?) and a darker brown one (dinos?) on the GHA.
microscope would distinguish. whiter light picture may show the green better.

Thanks, I'm 100% certain there is no hair algae in the tank, and the coral skelton was pure white yesterday. Whatever is on it now got deposited there over a day.

Got a microscope today, I am almost certain they are small cell Amphidinium dinoflagellates
