Gravity can help, just lower the water line
or in more seriousness, RFUGF would work wonderfully.

FWIW I think details here will be more worthwhile than a simple 'yes its the slow flow'
IMO its just the flow of water over biological media. not the speed of the flow.
personally I think the rate of flow will be more about the lack of dead spots in the tank... not about the effectiveness of the filtration.
poo would not get caught in something that is biological filtration alone... surely by definition that would be mechanical filtration n'est-ce pas?
by this logic, bacteria would not colonize on something that is mechanical filtration alone... surely by definition that would be biological filtration n'est-ce pas?
No one else claimed that, either. The words "single" and "kind" hadn't even been typed into this thread.
A very long time ago I was looking at methods of better purifying water...not just filtering, but purifying. I found bio-sand filters being used in third world countries where very foul, polluted water is poured in and crystal clear drinking water is drawn off.
It occurred to me that what we're missing in our conventional aquarium filters is advanced biological filtration...beyond simple ammonia->nitrite>nitrates.
The beneficial bacteria colonies function best when the water flow is slow and the media (and the colonies) is left undisturbed. Hence the dedicated bio-filter. Separate mechanical filtration takes care of the large particulates and it is serviced frequently not only to remove the crud to prevent it breaking down into dissolved organic compounds, but also to prevent BB developing here instead of the bio-filter. The inlet tube for the bio-filter is positioned higher in the tank, which prevents most detritus from entering...still, a thin pad prevents any particulates from clogging the bio-media.
So with a larger volume of bio-media in a dedicated filter with slower water flow, we leverage bio-filtration to better purify the water.
In many ways this is akin to the bio-sand filters and live rock and deep sand in SW.
