I actually proposed this idea on a fish forum a while back, but it was shot down for potentially generating too much humidity. Maybe it would solve my problem, as I have too little.

Anyway, what if I took an exoterra food bowl and sawed off a chunk of it so that it has a flat edge. I'd then drill two holes in the tank about 1'' off the bottom and run a couple of pipes into the water bowl, connecting to a pump and a mini "sump" under the tank. This would ensure a constant supply of clean, running water even if the snake pooped in its water dish. (I'm kind of an aquarium freak, so I love DIY stuff like this.)

This is probably a crazy idea but figured I'd throw it out there.

And to respond to Willie76 (sorry a bit awkward at the forums):

It's my living room, unfortunately, so I'd have to humidify my whole apartment. And the problem is that the heat in my place is intense, so I usually leave some windows open when I go to work. I think it's this combination that makes it get so low. And we've been having crazy weather recently, so there have been times I've come home and my apartment feels like a rainforest cause the day randomly jumped 20 degrees. I'm gonna see if I can get by more with turning down the heat and keeping windows shut more, as we're starting to near spring.
