Thank you so much for taking the time to help!

Kaorte....i am getting about 91-92 temp reading on the substrate right over the heat pad...and about 79 on the substrate on the cool side. The ambient temp is 82 this morning and humidity 51%.

Montie..i read the caresheet and have a copy in the bathroom Some of these specifics are not covered.

Blackcrystal..i have no controller on the UTH..i here these zoomeds are good ones and work like they should.

Another newbie question....
Do i have to much substrate? i read it should be 1/2" - mine is like 2".
