I got my new t-stat (herpstat) and flexwatt (thanks to Matt at MG) and have set up my new sterilite tub. I have the flexwatt taped to the bottom of the tub using foil tape, and have the the thermostat probe taped directly to the bottom of the flexwatt, also using foil tape. The thermostat is set to 96 and that only translates to 82 degrees for the surface temp of the tub on the warm side.
