IMO that is a lot of flow going through your sump. A lot of people will use a closed loop or in tank powerheads such as Tunze or Seio or Maxijets to give more in tank flow. With that much flow it is also hard to control microbubbles coming back to your display.
For example on my 190g tank I have a closed loop being run by a sequence hammerhead pump (5800gph), 2 Tunze stream 6200 (5300gph X 2) and my return is a quiet one 5000 (1400gph). It gives me roughly 95 times turnover without accounting for any head loss in the pumps which won't be that much as everything is under my tank.
