Hondo nailed it,
10X for a softie and FO tank...and as much as you can for a SPS tank.
My friend runs a sump/return and a closed loop...he is right around 30X......he is even considering a surge as well!
For me, my turnover is 26 X. Maybe a bit less b/c of PH is running the skimmer. But it's up there!

Turnover can be looked at as both internal and external.
Internally - you want enough water movement to circulate the water around the tank. No dead spots, especially behind any rockwork on in the corners. Some use powerheads to assist.
Externally - you want enough water leaving and entering the tank , by way of the overflow(s), sump and any filtration you may have down there, through the return pump and back up to the display tank. You may have some filtration in the sump or you may not.
I don't think there's any magic number for turnover - it may be different for each person's tank.
More is better than not enough obviously.
I vary mine in my 75 tank as well, but do not use powerheads.
Minimum - estimated at 500 gph
Maximum - estimated at 1,300 gph
All through the overflows and sump.
1300 gph = 21+ gallons per minute. It hums along nicely at that rate.

That would be 100 times turnover per hour.
Think you got 1 extra zero in there
25,000 gph would take something like 6 or 8" piping, and one bigass return pump.
100 turns per hour - stand back and get some towels ready and Lord help any fish in there
But I bet you'd not have any "dead-spots"
