So sorry about disappearing! Life got in the way! :P

The tank wall is about 1 to 1.5" thick because of the Great Stuff foam that I used to do my tank background. I was thinking that I don't really need to heat it 10 degrees. I know my frogs don't seem to like it above 75 degrees, but I think my heat mat might work now that I have thought about it some more. Plus, my room seems to stay fairly warm when I keep it closed off from the rest of the house.

So, I am editing my question to:
Which brand of heat mat should I use? What are your experiences with said heat mats?
