Help with Overflow Box!

[raw04f]

Ok so I'm settin up a 75 gallon tank with a wet dry filter and trying to buy an over flow box. Is it nessicarily better to have a larger overflow box than a smaller one (like women say), or does size matter? I found one online and wanted to see what you all think about it. Also any suggestions where I can buy a cheap and effecient overflow box would be great.


Here is one I found on Ebay, would this one work?

size generally doesnt matter. The limiting factor of overflows is the drain line size.

a 1" drain can only handle 600-700 gph, no matter how big it is.

the main reason to have a bigger overflow, is to have more surface area to surface skim.

The one posed will work but you can also find larger ones in the selling forums for about the same price and some times less.
