But I think a focus on a "tank turnover rate" is not a primary concern, but rather something that you just might consider when choosing or designing a scrubber. On a larger tank, a wider scrubber means higher overall flow.
Yes & no.

Two tanks, both 800 litres, both fed 2 cubes per day.

Tank #1 uses a 2 cube 6” screen scrubber with a flow over rate of 800 L/hour, which = TTR of 24 per 24 hours

Tank #2 uses a 2 cube 12” screen scrubber with a flow over rate of 1,600 L/hour which = TTR of 48 per 24 hours

The filtering capacity of scrubber #2 is theoretically twice that of scrubber #1 because Tank #2 has twice the TTR per 24 hours, and achieved this without increasing the speed of flow over the screen.
