Thanks again for all the helpful information.
I'm going to take the probe out right now,but I have two questions.
A) The thermostat is a Zilla thermostat, I think the probe might be plastic. Will it melt if I put it between the heat pad and the glass?
B) I'm using a Zoo Med heat pad, the directions on the back say that if i remove it from the glass it will damage the internal wires. Thoughts? Should I go buy another heat pad?
