For heavy stocking atleast 90 gal sump, with as much bio media that you can fit. You may also want to consider an auto water changer for that many aro's in a 6', it would help your water quality greatly and make your life way easier.
Yeah, I could use one of those as well. My tanks are beginning to take over all of my spare time. I am spending 2 - 3 hours each night on them; I think I'm getting a little too carried away with this hobby. Too much of a good thing?
