Has anyone ever seen this stuff? It is quite hard when in the tank and even after it dries is hard to get off rock. I had some on a rock and dried the rock out a while back. Haven't seen it anywhere else just wondering if anyone knows anything about it.

I've had that when exposed to the light mine turns red.
