I don't have a pic of this handy, but I'll try to explain it. Like if you look at the outside of your tank, right at the bottom you'll see a couple inches of substrate. You want the heat mat to be adhered to the side of the tank, but above where you can see the substrate. You don't want to line it up with the bottom of the tank where it'll directly heat the substrate itself, if that makes sense.
