Could I have a tub set up like this....

11" flex watt set at correct temps, 90-95. On the bottom for tummy heat.

Regular small heat pad mounted on the side of the tub to keep the air temps warmer, since it can get a little chilly here in my room sometimes.

I didn't know if it would work or not, and I was thinking it wouldn't matter how hot it got since he wouldn't be touching it. Should I still have it on a dimmer? And get it to what temp?

Thanks a lot!
