I got my first BP a few days ago, and after a lot of modifications to his 10 gal tub, I'm finally getting the temperatures to where they roughly should be. However, I have two problems. First, there isn't much of a gradient to the temps. Both the ambient and cool temps are at 81 F. The UTH I'm using for his basking spot is at 95 F but I don't think it adds any heat to the enclosure. I know 81 F isn't dangerous, but I from what I've read a good temp gradient helps a lot with thermoregulation. Second, the surface temps I'm reading from my IR thermometer are much lower than the air temps (roughly 70 F all around). Should I worry more about surface temp than air temp, or am I overthinking things? Any help is appreciated.
