So had to do some modification, the mount the Kessil AP9X has, only place for it to go was my overflow, which meant I couldn't use my overflow cover and made making a lid for this tank next to impossible without having some gaps that fish could jump through. So I did something I don't like to do, but I used a 1x6 and glued it to the back of the tank with it coming above the tank, and mounted the light to that. That way I can use my overflow cover, so no chance of fish jumping in there and made the lid perfect, I think it looks really clean. Pretty happy with how it turned out.
