I have a 340 gallon in wall display. I have 4 gyres: 2 x Maxspect XF 350s at the surface of one end of the tank. 2 X Maxspect XF 280s (rated at 6000+ gph each) on the opposite side of my tank at the surface. Those are all controlled by the Hydros wave engine now. Which is awesome! I run all 4 at around 60-70%, would like to do 100% to get the max flow, but, it's not good for my LPS. lol.
I have two MP40s on the back glass pushing water forward, those are both running at around 60% each as well.
My return pump is also running at the max overflow rate of my H2O Overflow system at around 2400 GPH. Which is around 8 times turnover rate an hour. In total with everything running at 60-80% I'm getting around 20-25k circulation on a 340 gallon display. Not the 100X I would like, but close enough.
