I noticed this in my tank about a week ago and keeps getting worse. It’s upsetting all my coral on the ground and even a few on the rocks. At first I thought it was dinos but now I think it might be cyano if cyano can be brown. I will include pics and there is also a bunch of stringy stuff almost like spider webs coming out of my zoas. (Not the heads but the bases) if anyone can figure out what it is for me and what the best course of action would be to get rid of this. Thanks in advance
