OK... I will try the UTH on the table and put everything in the tub as it will be when the tub is fully setup and see what happens... I am concerned that the added weight in the tub will make it bow downwards touching the UTH and possibly overheating the snake if it is turned up higher. I will try this first and see if it works, if not, I will attach the UTH to the tub and set it lower.

Thanks for your help!
