Really? How's it supposed to control or know the temperature in the tank then?

By attaching the probe directly to the UTH, you can control the temperature of the UTH, then you your thermometer to set the thermostat to the right setting.

I've got the cord, just before the probe, duct-taped down to the glass for exactly that reason. Snake moved it once. I said "Oh, no, you won't outsmart me."

Are there any other risks of keeping it inside?

The tape isn't inside the cage right? Tape inside the cage is a major no no.

That's what I'm saying! LoL.



I doubt it. I mentioned that I thought I had things set up properly before when it was just the Accurite and light-switch dimmer, I think. I haven't had this trouble getting the temps stable before, but I guess I was only looking at one temp reading and assuming that I could reasonably trust it at that time. I just got the Hydrofarm a couple days ago.



Ok, I'm stupid. Explain what you mean by that.

Meaning that you shouldn't use the thermostat to measure temperature. The thermostat needs to be set to the temperature that makes the cage the right temperature. for most of my cages my thermostats are set at 100-102.5 degrees to create a 90 degree hotspot. Try to think of the thermostat set temperature as a number and not as a temperature.
