I agree, 72 is way too low. I have been trying to keep my ambient temp as close to 80 as possible, which has worked fine til this week. Because she just ate, I have had the heat on all day even though I was at school all morning. I am going to look into replacing my UTH because I got it second hand from the person who gave me the tank because the UTH fit the tank bottom perfectly, but I think it's just not cutting it.

What would you guys recommend I try as far as insulation? My tank is fiberglass with a sliding glass front and a mesh vent running down the middle of the top. There is a 150 watt red bulb on top, a large UTH on the bottom of one side, and a small UTH on the side in a corner for the hottest spot, which is about 90 degrees IF it is in the neighborhood of 70 degrees in the room, which I am currently maintaining until I find a solution.

As I predicted, she did not move from her humid hide last night, which is in the middle of her tank, so at ambient temp. I would be less concerned if she at least curled up in the warm hide to digest like she normally does, but I guess it's her decision, not mine. I'm just keeping the room warm to be sure.
