I want to make sure I understand you correctly. Are you saying you hot glue the thermometer probe to the glass under the hide (so the probe is covered by the substrate)? If so, how do you make sure the snake doesn't get caught in the probe's cord (do you glue the cord to the wall of the tank)? Also, when you say you put thermostate probe between the UTH and the tank glass, are you saying that the probe goes on the bottom (outside) of the tank between the UTH and the glass? If so, I'm not going to be able to do that because I've already attached the UTH to the tank and unattaching it ruins it.
If I attach the thermometer probes directly to the glass, under the substrate (and under the hides), what temperatures should I be shooting for?
Thanks for your response.
