First of all, :welcome:
Is the 75 the Display or the wet/dry? The general consensus on turnover in the sump is from 5 to 10x turnover. Most reefers use a sump nowdays ( with a skimmer) as wet/dry with bioballs can be a cause of high nitrates if not mainained properly.

Trido has it nailed pretty good. but my rule of thought is that you run your overflows to capacity. so a 1" O/F usually drains from 600-650gph. so if you have one o/f push it o the max. and if you find you need more flow, then look at powerheads and such....

If the system is going to be fish-only then a wet/dry setup with traditional bioballs would be fine. If the system will be a reef (or will likely be converted to one in the near future) then, personally, I would set it up with live rock in the display and a good skimmer in the sump (ie. no wet/dry, no bioballs). Actually, I prefer the latter setup even for a FO tank myself.
As for using live rock rubble in place of bioballs in a wet/dry setup, although it might give some benefit in the form of denitrification, personally I would avoid this type of setup. IME it's best to have live rock in the display where it can be periodically flushed with a powerhead to remove detritus build-up. I prefer to keep the sump devoid of rock or sand as it's far easier to clean out any settled detritus this way. IMO avoiding setups/situations where detritus can build-up makes it far easier to maintain water quality over the long term.

hey how come you aren't building a refugium instead of a wet/dry? I would think a fuge is easier to assemble than a wet/dry
isn't wet/dry outdated? X has one on his 75 and has crushed rubble rock in his wet dry and it seems ok, My understanding is that the rock must be submerged to be effective. I was under the impression that wet/dry's could be potentially trouble without maintaining the cleanliness of the balls. Why even have them to begin with?
Have you looked into fuge vs. wet/dry? just curious
