I am wondering what would be best for my 180 gallon bowfront. It is drilled for a single corner overflow but I wanted to either add a second overflow in the other corner or fill the holes (they are drilled at the back) and redrill for a ghost overflow.
What would be best?
Has anyone filled drilled holes in the back of a tank?
