I'm going to buy this: http://www.reptilebasics.com/thermos...nics-ve-300x2/ and I was wondering what the best way to secure the probe to the UTH? Do you put it right onto the back of the UTH?

Also are there any brands of UTH that fit better to the curve on sterlite tubs? I'm using zoomed and they stick alright, but there are streaks and areas of air that I cannot get out due to the slightly concave shape of the bottom of the tub.

And also for my temp probes for my digital thermometer can I use a hot glue gun to stick it to the inside of my enclosure on the bottom, or would that effect the temp reading?
