SO I ordered a johnson t stat to go along with my economy rack I am having temp reading discrepancies the probe from the thermostat says 95, i put it in the notch which is cut out in the back that goes under the tub. I put a temp prob inside and under the hide and it reads 100 which do I go off?

I turned down the stat so i would get a reading on the thermometer of 94. so now the thermostat reads 89, I guess the positioning gives it a 5 degree difference. based on the heat being trapped under hide.

I think i need a heat gun!!!
