coral excretions?

[snowlynx]

I have this brown stuff all over corals, even on the glass walls.

I did FE last week. Not sure if it's caulerpa that died and turned brown.

Trying to vacuum it out, some of it stuck to to the rock and frag plugs

Looks like diatoms, it'll go away eventually

That isn't coral mucus..

I've always thought that to be dinos vs diatoms...
