It is on a glass tank it will be in a zoomed dual deep dome. It is going to be mounted on a zilla bracket that hangs above the tank. There is a temp probe that is going to be attached to the back of the tank and to the basking site that runs the contoller/thermostat. It turns off at 87 degrees or whay ever it is set to by me.

If I got a rhp can it rest on the screen top?
