Help with Humidity!

[ksaul]

btw i don't think that's a 30 gallon i have a 30 myn is way bigger that looks like a 20 u only have 2 things in it and looks cramped

it most definitely is lol i had very large objects in it making it look small, but I replaced a lot of that setup. I added smaller more tight caves, a smaller water dish, aspen bedding some drift wood and more horizontal vines. I added a jungle background and did the toil foil treatment using a red 50w bulb at night on the cool side of the tank (hangs 10" above the opening).

I purchased a UTH from ZooMeds (fit of a 30g tank, about 1/3 of the tank) and the ZooMed Rheostat.

(Q1) Id rather have a thermostat that automatically adjusts to the floor temp but not sure what I need..
(Q2)I have the tank sitting ontop of my dresser with the UTH on the underside (obviously), but how much clearance does the UTH need below it? I dont want it to stain my dresser..
(Q3)Also Ive yet to get the probe/thermostat/humidistat controller & guages. Whats the best combo deal on the market for the best price?

Ive been reading the caresheets and FAQs but looking for what the community uses that I know has good results, not sure when the last time they were updated..

Thanks ladies & gets!
(Still using the old-school gauges and its reading at 78F with 62% Humidity)
