OK..so last night Aaron (theserpentmerchant) helped me out quite a bit....

Have a few small follow up questions....

I have two thermometers...and a thermostat on the way....thermostat probe is going between the outside of the glass bottom and the UTH

My plan is to have one thermometer on the side where I have my hot spot...the other way is going in the cooler side....What method of attachment is best for the probes? Obviously tape is a no go...I was thinking a hot glue gun? ( I am currently using a 10 gal glass tank).

My second question is placement of thermometer probes....between substrate and glass bottom or more on top of the substrate?

Thanks!!
