Thanks for the reply. She is in the finished part of the basement where we hangout the most durning the evening and all the entertainment is at, tv/xboxs/my workstation desk area. So I think when we are not down there and everything is off it's getting to the lowers 70's. My guess 72ish and yes I did have to add a CHE on top of her tank because the UTH was not able to keep the air temp ~80. Before she was delivered to us from the breeder and I was testing things. I had to crank up the UTH thermostat to like 103 to register 75 air temp and I thought to myself nope, that's getting too hot and went out the local pet store and bought a 60 watt CHE and put it on it's own thermostat which is set to 78. That's why I was looking at the herpstat 2 so I can run the UTH and CHE on it.
