I’ve got an area in my tank that has had this growth for some time, but it has stayed on the underside of the rocks and wasn’t a problem. I assume it’s some sort of sponge growth. It is now moving up the side of the rocks and starting to grow on the shadow side of Acro’s on the edge of the rock.
is there a way to control it, make it recede back away from the corals. Pretty much impossible to take the rock out.
