Exoterra-first vivarium

[tb87]

This is first shot at this, been building with the help of a friend. I will try to keep the pictures in the best order I can. Its a pretty typical build from what I have seen on here. The water fall is my biggest question/concern. It was build from foam blocks the covered in the Mapei Ultraflex 2 to create the rock look. Then painted in a non-toxic paint. The bowls where water collect are covered in a think layer of silicone per a video we watched. I am wondering what I should use to somewhat water proof the rest of the waterfall; or if I even need too. I intend to keep the RETF in here. If anyone has any insight please advise. Otherwise on to pics. (clickable thumbnails)

Finally got a lot of work done. The waterfall is in and everything is running. I need about 3 more plants. I'm still not sure what kind of animals to put in. I would like to pick up a couple retf but wonder if I have enough room. Any questions or comments are welcome.
