I got my rock and sand both from reefrocks and had no issues with the product. PITA with shipping though, I had to email and call a few times because my order was not showing up. Owner blamed it on having new warehouse employees who were screwing things up, but who knows. After a month I got my order. Really nice sand I thought, although I wasn't sure if it was live or not. It came shipped not wet in liquid, but damp. When I got my rock they had some deal where you got free sand. I gave it a good rinse before I put it in tank.
