Cool side still isn't warm enough...

Well, there's your problem right there. Even with a second UTH, you may struggle to keep ambient temps warm enough and need to add overhead lights...which will play havoc with your humidity.

Why struggle THIS hard with an unnecessarily large tank? If you want those temps in the correct range, get yourself an appropriate sized plastic tub. You may not even need a second UTH if you do that....low humidity will cease to be an issue....cleaning is ever-so-much easier....much cheaper to warm overall than a huge glass tank......etc etc etc...

then that $50 i spent on the glass tank would be completely a waste

ur saying another UTH wouldnt be able to get my temp on the cool side up only 8 degrees?
