A lot of people use Zoo-Med UTH's but mine even using a cheap rheostat from petco still reads 114 when on low. I even checked it with a infared handheld thermometer. is this normal or should I take it back? I use the accurite thermometer from walmart with the probe directly on the glass just a described from the tank setup in the sticky. He seems happy and has even ate in the 2 weeks we have had him. He comes out at night and we can handle him no problems every couple of days. Basically why I'm posting is of course I use a bulb to warm the tank but its killing my humidity. I can only maintain 30-35%!
