I have currently a 10 gallon tank for my BP and it may be a while before I can upgrade him to a nice enclosed large tank he'll be in when he's larger, but I have a thermostat ready for when I have the UTH (currently using heat lamp). Is it a bad idea to use the UTH on a glass tank if I have a thermostat? I also have an electronic heater that measures both sides of his tank seperately.
