FYI on the
UTH, the manufacturer says that these are "for use on standard glass aquariums only: no acrylic, no metal, no wood, no plastic, no foam, no fiberglass, no stone cages" They have to have plenty of circulation underneath so they don't burn your furninture. The manuf. actually recomends side mounting it. For those of you lucky enough

to have your house thermostat at a decent temp, a
UTH is probably enough. At
my place (where it's like a freekin' ice box) I have to use a
che also. I've got them both on a thermostat and it works great. To paraphrase: Useing multiple
UTH's under one tank or a larger size
uth on a smaller tank can cause stress cracks. Kind of long winded, I know, but I have one of these and they're very specific about installation.

Hope it helps.

I accidentally posted this in the linked thread also. oops.
