Just wanted to pick everyones brain and see if my set up is ok or if i need some adjusting. My tank is set up with a UTH on the hotside, attached to a rheostat, with the hide over top of the UTH I have a thermometer probe mounted to the inside of that hide so it hangs just above the substrate which is aspen. I have a thermometer in the middle of the tank to measure ambient air and then another hide on the cool side with a probe inside that hide just laying on the substrate. On average the hot hide measures at 90 the ambient is 84 during the day with a little dip at night but the temp in the cool hide is showing maxed out at 78. The tank also has a 75watt red light heat bulb. My concern is that cool hide is too low the problem i have is when i cover more of the lid to keep some heat in the hotspot temp can jump to 92 or more and my rheostat is already turned down to the lowest possible setting. Looking for options to bump the cool hide temp a few degrees without over cooking the hot hide. Any and all advice welcome.
