That UTH is going to be too big for this tank. It shouldn't cover more than a third of the tank. If it's covering 3/4 of the tank there will be no heat gradient. Also you can just tape (aluminum tape works) a uth to the bottom of the tank instead of using the adhesive. If you're going to switch soon you could probably get away with taping it to the bottom of the 10 gal so that it only covers a third of the bottom instead of putting it fully under the tank. As for the analog thermometers.... try to never use tape inside the enclosure and you might as well not even bother anyways because they are pretty much useless. you really should have a digital. They don't cost much more anyways. There also shouldn't really be a need for the heat lamp at all in such a small tank. All that it's gonna do is suck out the humidity.
The clips can be a bit tricky. If they're the flat bendy metal ones then you just have to muscle them so that the little hook slips under the metal on the top of the screen cover
anyone have any input on the bugs?
