Thanks. Yeah, I took that picture last night. That 136 was the temperature of the UTH. The sensor is under the substrate right on top of the heater which is under the glass. The people over at the RedTailBoa forums told me to unplug it because it was way to hot, so I did. I ordered a Electronic BAH-1000 Thermostat... that should be here soon, until then I'm just using the CHE on top and that's all. I'm not using anything to control the temperature of the UTH. What do you guys suggest about the CHE? It doesen't seem like it is making the hot side hot enough.
