Wonder if petco is going to have sand on sale, sometimes it's crazy cheap there, and I think I'm going to put sand in my anemone tank just to keep the anemones on rocks and off the bottom glass (probably can't do anything about the side glass). Although looking there they do have some on sale but damnit if they don't say what's in it, CaribSea Super Naturals? Imaginarium? I've been so out of using sand I don't even know what half this crap is.
