Need a overflow box, which size?

[Blue Spot Octopus]

I have a new euro brace 72X30X24" tank and it has already been drilled for a Modular Marine overflow, which size should I get. So far I have an ATB 1500 return pump or a Fluval SP4 pump. I am not sure of which one I will use. Thanks in advance

The longer the weir the more surface skimming you will get. It would be good to get one thats larger than what your pump can dish out in case you get a larger pump down the road.

I have the 32" model from them on my 72X30X24 and its AMAZING! moves a TON of water and DEAD SILENT! the first week the tank was running about every day after i got home from work i would freak out thinking the tank isn't running, but it was lol
