Thanks for the diagram, and i will be using two thermostats, i think im gonna go for the zilla thermostat, because i like how it looks and ive seen plenty of good reviews, so just tape the probe to the non-sticky side of the heat pad? I didnt think that part got hot but thank you, also, a question totally unrelated to temperatures, what kind of water do you give to your reptiles? I use bottled water that i get at walmart, not tap water, but ive seen a product called reptisafe and it says it makes the water safe and better for reptiles
