Hey, I've got at least that much to sell in my tank. I probably have between 40-50lbs, but am willing to sell less. How does $3/lb sound? Some of the rock is homemade from aragonite gravel, so it's big pieces, with nice arches. It's got alot of purple corraline algae on it, and been in the tank for about 5 years. Let me know if you're interested, and I can try and get you a current picture. Let me know, and we can work out a deal!
