Ok a bit of set-up detail.... I have my thermostat (Ranco) hooked up to my UTH. The probe is in between the glass of the tank bottom and the UTH. I have it set at 94F. I also have a digital thermometer in the hide (terra cotta thing. It is the thing you set the pot in to hold the water. It is painted.) just above the substrate (cypress). My thermometer has different readings all the time. They range from 92 degrees all the way to 101. When it gets high I will lift the hide and let it air out. I have tried changing the settings on the thermostat but still getthe same results.

So my questions... how can I change this? Is it bad that the temps get the high?
