the above is correct
in addition to the above:
Amount of return g/hr is not as important as internal flow, i.e. flow in display tank. And what we have in our tanks is still nothing compare to the ocean currents, i have almost x200 times flow in my 60 gal, but only less then 300 g/hr return from the sump.
