I'm considering getting into the group buy at BRS, and buying some dry rock. It will cost about $2.30 a pound, but figure I will check here and see if anybody has some locally they want to sell first. I can use dry or live. Granted, if it is live and has crap all over it, I will likely have to just dry it out to kill it off...but can still use it. I can use plenty of it, so I'm not all that picky about the shape or size.
