Yes I have my uth and Che both on the thermostat. What I read said that I could do it that way, but I'll look into a dimmer and get one. And as far the temp gun and digital hydrometers, I order them offline last night, so they should be here by next week. I have two digital thermometers already. And yes my uth is stuck down, where should I place my probe exactly on the outside?

Thanks for for all the feedback.
