how many gallons per hour do you need for a 150 gallon aquarium with a 50 gallon sump/refugium

what are planning on keeping? fish only, lps, sps?

sps 40x turnover 8000 gph

lps 30x 6000 gph

fowlr 20x 4000 gph

imho

If I understand you correctly, you're just asking about how much water your return pump should be pushing. I've heard 4-5x your total water volume used as a recommendation for a return pump, and that sounds like a pretty good rule of thumb to me. It'll give you a good turnover rate between your sump and DT, allowing your skimmer and whatever else is down there to do its job. The relatively low flow will help keep things quieter. Also, if you plan on making part of your sump into a refugium, you generally don't want a real high flow through that area.

General rule is 3 - 5x display size. Typically, an average sump is ~ 1/3 the size of the display, so you are right there. I'd say 450 - 750 GPH actual flow. It also depends on the overflow. It has to be able to handle the GPH.
