My undertank heaters are on the side and I will be honest it was a pain to reach my temps. Alot people don't use bulbs I think because they say they are to drying but you got that reptifogger so that wont be a problem for you, And ya I had to go out and buy abit higher stand to put my tank on so he could get enough light. My pacman Im getting soon will be getting a ceramic heat emitter. Enjoy your new froggy, I got one last year at the end of august and im hooked now.
