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.
