So I'm wondering....how much circulation....gph should a fish tank have? I'm pretty sure I dont have enough right now, but I also only have 100lbs live rock in a 90 gal tank....so it's probably not the most important thing just yet. But I'm planning on redoing my regium/sump and adding a large pump down there to do it all with a loop system up top...but then i wonder, hm, how much is enough?
