I just had a few questions, first the thermostat for the UTH should I put it on the underside of the tank between the glass and the heater? I'm a little concerned about putting in the substrate as I don't want my BP to disturb it and I get inaccurate readings. Second I'm having a hard time getting the ambient temp of the tank in range. it hovers right at 76-77. He's housed in a 40 breeder with plastic covering half of the top to retain heat already I don't know if adding a small red light or ceramic heat emitter would make it too hot but I'm a little concerned. His cage is in my basement which tends to stay on the cooler side around 70 or so in the summer. Any input would be appreciated.
