About 18 months ago, I glued a GSP frag to my back wall. It’s grown to take over a large space but only a small portion has green extended polyps. About 90% of it is just black growth with no green polyps. Has anyone ever seen this? I’m confused why this doesn’t look like a green lawn.

Thanks in advance for your attention!
