Hi I just got a infrared temp gun and added a UTH on the cool side of my bp's tank and I can't seem to get the temps right. I was using dial thermometers but I bought digital ones and placed them close to the bottom of the tank. I was using a 50 WATT red lamp for the warm side in addition to the UTH on that side but I've turned it off since adding the 2nd UTH. The ambient temps have been too cool, I think, 78-80 on the warm side but the cool side was 74 when I woke up this morning. How can I raise the ambient temp? Or do I need to at night? During the day the AC will kick on in my house but the room temp will still raise to at least 76 so the tank will be warmer I assume.

Also, this morning the temp under the cool hide is 90 and under the warm side it's 98, measuring with my temp gun. During the night I woke several times to check the temps and the warm side was 90 or so under the hide and the cool side under the hide was 80-84. The substrate outside of the hides are lower, so do I go by the temp under the hide only? I have the UTH on a dimmer, on low. The warm side UTH was just plugged into the wall. I plugged the warm side UTH into the dimmer but I'm worried about how to keep my ambient temps up now.

It's a glass tank with aspen bedding. I've never seen him burrow. I can post pictures in a bit if that will help answer any questions. I have to take my son to school first.

Thank you for any help.
