The bacteria need to break down nitrates live deep in the rock in areas that achieve almost zero water flow (causing extremely low oxygen conditions). Live rock is porous and there are area within the rock that water can barely contact to reach this bacteria. By the time it gets there, the oxygen in the water has been used up by other bacteria. As a result, the bacteria is slow acting. You can not duplicate this type of bacteria in a filter because the water flow is much to higher to allow this type of bacteria to live.
