How to heat tub

[CrocodileFace]

Heat mat + t-stat or heat tape + t-stat, BP really benefit from belly heat and additionally I would stay away from lights when using a tub, even if 10 inches away something could happen it could be tips over and it would be a disaster.

Best Heat mat in my opinion http://www.reptilebasics.com/ultratherm-heat_pads/

For a 41 quarts tub a 6x11 or 11x11 will do just fine.

Okay... I have a thermostat already but would you really not need to use one with these like it says?

Thanks for ur help!
