We don't *really* use the sticky thermometer on the back. It's just kind of... there. We use the digi with the probe to moniter both sides of the tank.

I'm kind of pushing for a clear tub... it just kind of stinks with all the work/money we've put into the glass one so far.. I know it will be less of a headache for us if we were to get a plastic tub, and less stressful for her. I just have to convince the masses..: I keep thinking... Easier on us? Better for her? Let's do it!!
