Can anyone help me figure out what this is? Tank is about a year and a half old. I'm afraid it might be dinos but it's not stringy. I used chemiclean thinking it was cyano but it did nothing to it. Under white lights it's brown. With blues, it looks like a dark red. when testing nothing is out of the ordinary except nitrates and phosphates being low. (which is why I suspect dinos). It also doesn't go away when lights are off.
Could dinos make my corals close up? It started off with my duncan. It's been a few weeks of it looking like this. I don't know what to do at this point
