Ok, my temps are right but with infared lights, the light actually heats things up. The infared light heats things up. Thats why the water gets so hot. My temps are 90-93 on the hot side and 76-80 on the cool side. But when you put the water right under the light it heats up. I primary source for heat on the hot side is a UTH and the light goes right in the middle to keeep the over all temps just right. I decided to move the water to the cool side and just spray the tank a few times a day.
