I was previously using Sterilite 6qt tubs set on top of flex-watt tape, controlled by a thermostat with a dimmer in between so that the tape never got above 90F. Now I have moved my 3 snakes into a rack. In order to keep the temps in the 80-85 range, I have had to eliminate the dimmer and only have the thermostat. The probe I have on the tape now reads a max temp of 100-102F, but for only about 1 minute out of every 10 or so. The average temp of the tape is 93-98F. Is this temp too high? If so, how would I reduce the tape temp while still maintaining the tub temps?
