Thank you for the info about the placement of the probe.

When I get home tonight I will be placing it between the UTH and the glass. Do you think using some Gorilla duct tape will be fine to help adhere the side where the probe is inserted under the heat mat? I read that the gorilla duct tape can take high temps, but I can get whatever tape will work better. Its a smaller probe, but I just want to make sure that the UTH stays adhered to the bottom of the tank.

Thanks!
