What size pump would be best for a 90 gallon tank?

capsgirl70

I have a 90 gallon tank with young fancy goldfish as the only inhabitants. I am going to switch to an overhead sump for this tank, but wanted some input on what pump you would use for a tank this size. What would be the max gph?
Thanks!

I think i would at least shoot for something like 300-500gph at a minimum, so at least the possibility of the water being cycled through 3-5 times an hour. How big is the sump tank?

900 gph or more for goldfish.
