Outside surface of bottom of tub/tank -> UTH -> probe -> small square of styrofoam -> heat-safe tape to hold the styrofoam in place

I also tape down a section of the probe's cord so that the probe can't get tugged out from under the styrofoam square. With this arrangement, I have my Herpstat set to 88.0 F, and find that the surface temp for the hot spot (measured with an infrared thermometer, as fadingdaylight recommended) matches up pretty closely, right between 88-90 F.
Finally got my therm hooked up! I made a cardboard lid cover and lined it with foil underneath and put black duct tape on the top so it did not look quite as hokie lol. I used your sandwich idea for the probe so I did not have to try and unstick the UTH. Thank you for that awesome idea. I'm hoping that with this new cover, I will be able to retain some humidity. Right now, I will missed it in the evenings and it will be back down in the '30s within 24 hours.
