Alright guys, I need a little help. I've got an under tank heat pad, hooked up to a rheostat. (I wanted the thermostat, but petsmart didnt have one, I'm gonna switch when I get the cash moneys) The temps on the hot side are good, and the temps on the low side are good when I put a light on it, but just under the substrate, on the glass above the pad, the temps get to about 91 degrees. I know this is above 90 degrees, the cut off, but do you guys thing my snake will go all the way down to the glass? He will get here today, and I wouldn't have ordered him but I thought I had everything set up, but seemed to overlook this. Plus, with the light off, the cold side doesnt stay hot enough, even though the hot side seems too hot. I would like to find some way besides the lamp to keep it in the right temps, because I like to sleep, and the viv is in my room ;] Sorry this is a little long winded, and THANKS FOR THE HELP!
