Ricky and Taylor, thank you very much for the info.

I read through that post a few times, but I still have a couple questions.

So today I will take apart my tank and start over by putting the probe for the UTH thermostat outside the tank. Then I will order the thermometer you guys linked off amazon so I can have one with the probe. But according to the guide at the end when he's talking about measuring the temps he refers to knowing both sides temps but on the instructions he's only using one probe that he puts on the hot side above the UTH under the substrate... How am I supposed to know what the other temps are in the tank like on the cold side that is supposed to be 80ish?

Do I need two one for each side or no?
