I bought a UTH that says it can be used on either the underside or the side of tanks. From what I've seen most people here like to place it under their tanks, but my tank's sitting on top of a flat surface. I'm afraid that putting the UTH underneath won't allow circulation and either cause a fire hazard or at the very least damage/burn the wood. The instructions say that the "side-mount" option is actually better, so will I be okay doing that?
(I'm also using an infrared light for heat as well as a basking spot lamp.)
