What kind of uth or heat tape should I get?

[The Serpent Merchant]

For a glass tank I wouldn't advise heat tape.

I would get an ultratherm UTH: http://www.reptilebasics.com/ultratherm-heat-pads

Make sure that it is regulated by a good thermostat, they are not optional when it comes to UTH's.

Here are 3 good thermostats:
