I use under tank heating as well as a ceramic basking light. Together they make the warm end of the tank around 85 and the cool end in the low 70's. I have the ceramic basking light on a timer, so it goes off at night, but the under tank heating stays on. This cools the air slightly, but doesn't allow the tank to get below 73F or so.
