Using travertine for substrate instead of none or sand.

[my2rotties]

Here are a couple of pics from my camera phone. This is just the start of the project for now. We are still on the fence with the bottom of the tank. I put a pic of the 1"x1" and then the 12"x12". On the back there are some live rocks that have been cut on the tile saw for shelves and such. It is not complete yet. So far we have used three tubes of silicone, and have the overflows to clad in travertine as well as the bottom (if we do so). My husband is no where near completed so he will be mad that I posted pics so soon...
