have a question? are you using an UTH (under tank heater) pad or just the light as a heat source? if you're using an UTH, then the probe should be placed on the glass above the UTH to get an actual reading from the pad. Those things can get as high as 125 degrees (perhaps more), enough to burn a belly if the bp should get between the glass and the carpeting.

here is a link to the sticky on this forum about setting up a glass tank for a bp
