It is set up with belly heat. Each level has its own 11" flex watt panel, with about 3/16" gap between the tub and heat. It seems to be pretty consistantly 90 on the warm side. It is a bunch of wood screwed together. I am more worried about function. I am not putting it on display or I would have built display cages.

Here is the site I got most of the ideas from. He used the cb-110 tubs.
