Switching to tub. (another one of these threads)

[omnibus2]

If the heat pad is hot enough to heat the tank I would assume that it would be hot enough to use for a tub, but you have to make sure that it is properly controlled. Yes, you could use a soldering iron to melt, or drill, a hole large enough for your temperature probe to fit through, but I would put it in the side so the probe could stay in the tub when the lid is off. There are many good tubs out there. I really like Iris tubs, but I also use Sterilite.

Thanks for the reply.

My ambient temps are lower than ideal; when I put my finger to the glass (don't worry it is covered with bedding) it is hot, so I assume the uth is doing it's job. I guess the glass tank isn't doing a good job of maintaining the heat.
The thing is that the uth's instructions say specifically only to use with glass, and not plastic, so I don't want to risk it.
