I have a Mars commercial tank that has two 2" drains in the bottom of the tank. Originally the tank was divided into three sections. Return in the center with water cascading into both sides. The water drained from each side with a 2" stand pipe inside of a black overflow box that was attached to the back glass. The pipe comes into the box thru the bottom. I removed the dividers, raised the boxes up and raised the standpipes a few inches with a stockman type silencer. Everything works as it should except the pipe sticks out of the aquarium about 2" which is making it difficult to secure with a screen top. A 2" Durso will not fit in the overflow box so that is why I went with a stockman. The holes are too far away from the corners to make a corner overflow. Anyone know where I can buy wider overflow boxes with holes in the bottom cheap, or a better way to use what I already have?
