Me and my dad took that into consideration when setting up the tank but even though it looks like a big overhang it’s actually hardly 1-1.5” on one each side and the weight is evenly distributed through the table. We did a lot of work to make sure it wouldn’t flood the house.If it was my tank, I'd have a lot more peace of mind if there was at least a piece of plywood under the tank. The overhanging edges seem like a disaster waiting to happen.
