Hey Pat, it's Paul Compton....Does your daughter still need rock? I've got a couple of pieces I could give her. Currently they're sitting in an empty tank (in water) that I'm not using. Its just 2 pieces, one of the pieces is about 5x5" the other piece is pretty large, kind of a weird shape, like s shelf with angles. Both pieces are dense. But could make nice base rock. If she still needs them, I'll give them to her. Otherwise they're just going to sit in my refugium (Which I don't need). Let me know. I'm working in Northville for the next few days so I can drop them off. Are you going to the frag swap next weekend?
