I recently got my 75 gal tank all setup for my 18 week old beardie. I have a 100 watt basking light and a 36" reptisun 10.0 fluorescent light. The temp and the warm side is around 80 and the cool side 70-75 imy house is a little on the cooler side this time of year. So I'm thinking of heating a CHE but not sure what wattage and also do the che's need a ceramic clamp lamp? Also is it better to put them in the tank? Or is it fine on the lid? I got ceramic tile as substrate and my beardie just stays under the basking light most of the day, I'll put him on the ground but he'll eventually make his way back up to the basking spot.
