I don't have a ton of experience with drilled tanks so I'm a little confused about how I would go about setting up an overflow on a tank that is drilled where this one is. It's drilled on the back and bottom and I have no experience with that. I attached an awfully drawn pic because I'm terrible at explaining things. It's a 45 gallon acrylic tank and if I purchased it what would be the best way to add an overflow when the tank is drilled where this one is?
Thanks!!
