Have to say all of this looks great on how you are improving the enclosure. The UTH (heat pad) needs to be on a rheostat so you can regulate the temperature of it. 97 is a little high for the warm end. You want the warm end to be around 90 and the cool end to be around 82-84 (that I've read). Do you have any way of knowing the temperature of both ends of the viv? Also, are you still using the light inside the enclosure?
