Ok. I have a 20 gallon long aquarium and a UTH installed on one side of the tank and yesterday I got an Accu Rite Indoor/Outdoor thermometer that also read humidity level. My main question is, is where to place the probe inside the tank to get a proper reading.

My other concern is that before the UTH my BP was trying to get close to the heat lamp, but since I replaced that with a regular daylight bulb and installed the UTH, he hangs out most of the time day and night on his hide which is in the tank on the opposite side of the UTH. Also since I've had the UTH in the tank (about 3 days now) he comes out and keeps getting in his water bowl constantly. I felt the tank end with the UTH and you can feel it is just barely warm, so I don't think I have the rheostat turned up too high as I have it almost on Medium from low.

Any suggestions or theories? Thanks guys!
