    Anyone have grey coralline? I know it comes in all kinds of colors. .. but I have what looks like grey coralline unless their is some sort of reef mold I'm un aware of. It's growing in spot patterns like coraline but only on rocks.

    I have some of what sounds like what you're describing in my tank. I has a smooth grayish/tan colored coralline look and it grows in small patches.

    At first I thought it was some sort of sponge - but it's hard as a rock. Next I considered it might be some sort of smooth SPS, but it has no polyps I can see. It almost looks like my Blueridge coral, but again, it has no polyps.

    I'll try and get a photo of some of it
