Ok so now I'm a bit confused. I have my thermostat setup on bottom of tank with ultratherm UTH pressed against it. Thermometer under substrate. Reading showing 91/73 ( I know the cool side is too cool and will work on that) but when I test the heating area with my infrared digital thermometer reads much cooler. It's a cheap handheld thermometer but when I test it around the house it seems about right. I'm kinda new at this so just making sure I'm not missing something...
