Uth

[Evenstar]

If you do decide to go with a UTH, Reptile Basics also sells the Ultratherm. That is a much better choice than a Zoo-Med. Better quality, better price, very safe.

Because of the wiring involved with flexwatt, I would stick with a uth for a single tub. The flexwatt really becomes economical and practical with multi-tub setups and racks. But to each their own and its certainly not wrong to use flexwatt with a single tub. Just thought I'd offer another perspective.

Reptile basics will wire it for free so it really isn't a big deal.

would a 6"x11" ultra therm be big enough for a 23x16x6 tub?

Yes it would, and would be a good choice for your set up, in my opinion.

Yes, that should be just about right. I agree with Slim that it would be a good choice for your setup.
