So, other than PVC and wood, what did you use to create your waterfall? I wanted to do mine in the one corner and then have a stream run diagonally to the other front corner. Was thinking about having a shallow "pond" in there.

I have beardies, and have heard of people using the blue or pink insulation board and using liquid nails to hold it together and then carving it. Once they were done, covering it with grout, and then sealing it. Was wondering if this method would be safe to use for frogs? Of course there is a certain type of grout and sealer they recommend you use that is supposed to be safe for critters. And you have to let it "air" for a while to allow the fumes to dissipate.

My Exo Terra cage came with one of those fake backgrounds that are made out of foam and are supposed to resemble rocks. I was thinking about using it instead of the great stuff foam to create my background. Its older anyways and not very pretty, so if i cut it up and cover it with black silicone and then eco earth, it wouldnt be a big loss if i screw up.
