Going to be drilling through the back of my tank since the bottom is tempered, and I'm looking for a thread or pictures of the best way to go about doing it. I was thinking I would build an overflow box around it. Its a 120g tank and going to be using 2" overflows. Was thinking I would do 2 in the middle or 1 in each corner or the tank (I'm assuming I would get better overall filtration with 1 in each back corner of the tank since it's drawing in water from 2 different points of the tank).
Open to suggestions, thanks.
