So I have a 20 gal long tank for my bp and a zoo med UTH for it. I also have a little thermostat probe that I stick between the tank and the UTH. The adhesive for the pad just doesn't seem to be cutting it, due to the bulge caused by the probe, the pad won't lay flat. I use aluminum tape to try and keep everything on but I still see the pad falling off. I was wondering if I should add some sort of padding, foam or something, under the tank to put pressure on the pad to help keep it on the bottom of the tank, but also slightly worried that would become a fire hazard. Any suggestions?
