By the way, it is important to make sure your sand is as close to the glass bottom as possible... as the rocks and sand settle in and critters dig through the sand.. the rock formataions may become unstable or unbalanced unless they are touching the bottom. I like the thin layer of sand first, because there is no heavy spot on the glass.. it's spread out.
