Center Overflow - Size question

[andresont]

"ReefReadY" center overflows are wide and almost flush wth the back wall.I don't remember exactly but i think it is only 3"(?) inch deep and like 12(?)"wide.
Seen one in J&L on a 120 Gal.

Thanks for the reply. I was thinking about having it in the center, and not near an end - it would be a custom tank. I am just concerned that having a big black box in the center of the tank will look horrible, and even more so if it is put against a wall.

I was hoping that someone would have, or have seen a tank with a center overflow and give me some feedback on what the 'proper' dimensions for a center overflow would be (ie how big the tank should be, for it to look okay).

I'm assuming you mean in the exact centre of the tank, not the centre against the back wall. I don't think there's a certain size of tank that's necessary, but keep in mind that at the smallest, the overflow would probably be 6"x6". So I guess you need to figure out how much space you want between the overflow and the glass.

I have been considering this as well for a new project, and would likely build up some rockwork around the overflow, so I wouldn't just have a big black overflow box jutting up in the middle of the tank.
