Hi! I finally got my infrared heat gun today and I scanned my guy’s tank just from the front to see from one end to the other it goes from 85-75 degrees! I tried top to bottom too but it didn’t change. I have a 150 watt basking light that is a week old as well as the sunblaster T5 reflector lamp and the corresponding light that goes in that as suggested in this group up that is also a week old. What else am I doing wrong that it’s not warm enough in his tank? He’s been under his hammock the last couple days so I was wondering if it’s too warm! Guess not. Help!
