Temperatures in ball python cage 13 Dec 05

I've just purchased a PE-2 temperature gun from Pro Exotics, and I did a temperature survey of my aquarium tonight. I took most of these shots from a distance of 2 to 6 inches from the surface being measured. With the PE-2's 8:1 ratio, I'm measuring quarter to three-quarter inch average surfaces. These temperatures are taken when the room temperature is a fairly steady 73 degrees F.

I have a UTH that runs constantly. I have another UTH against the left wall of the aquarium and a clamp lamp with 60 Watt black light bulb over this same warm side of the aquarium. The clamp lamp and side-mounted UTH are on a thermostat. The thermostat had kept them off for a couple of hours prior to the survey, but they came on as I began the survey.

I hadn't misted the aquarium in about 24 hours. Immediately after misting, temperatures would be much lower. Temperatures remain low for a couple of hours after misting.

Comments, particularly from experienced herpers, are welcome.

Thanks
