hello Kylie, I'm Kyle, nice to make your acquaintance.
as far as thermostats go shop around for a better price on one of these and order online. I got two for about 50 bucks after shipping, but I don't know if the place I ordered from will ship up north.

I also recommend a uth for easiest heat source, just place it on the ground under the tank with the thermostat probe in between and set it to about 85 and see where that leaves you and adjust accordingly.
