Size and sump design

[Nathan43]

I intend to build a 500 gallon aquarium (96x48x28) and have never set up a sump before. I have a spare 75 gallon and was wondering if this would be sufficient or would I need a 120 or 90/100 long? Also, if I can use my 75, would be be a could setup for it if anyone out there with monster tanks have any tricks of the trade. And is there a pump out there that can handle 3500gph+
Thanks

IMO a 75 gallon tank would work for a 500, but I would rather use a 100/125 to have the extra room and water volume.

There are plenty of pumps that will handle 3500gph.

I am using a reeflo pump. they are great and have excellent wattage ratings.

Okay, so how would you go about arranging the chambers in the sump and what media would work best?

This is one way;

One of my sumps for reference, post #1004 or so. Keep in mind, this is a two chamber setup. For a one chamber, you would just eliminate the divider between the two bio areas.
