Wow, a ton of awesome help here. Thanks to all! I'm definitely going to start looking into PVC enclosures for her. In the mean time, I'm going to get a thermostat for the UTH, a thermometer/hydrometer w/ probe, and I now know where to arrange them. I'm still stuck on one thing: I need more heat, so I'm thinking the 8x6" 8Watt UTH isn't cutting it, right? Since it's not on a thermostat, It's maxed all the time and not even close to hot enough. My 22gal tank is ~10" wide, so should I upgrade to the 8x12" 16watt UTH? Although it's bigger, does the doubling of the wattage mean it gets hotter? If I can get the smaller UTH off the bottom without breaking it, should I use it somewhere else in the tank, like the back or something? If I can get this temperature thing figured out, I think I'll be all set for now!
