Hey Marc,

IMO, I think if the system demands really that high of an effluent rate to cause a concern of pulling the system's pH low, the system would also have that much of buffering capacity to stabilize it.

In any event, I feel that a properly tuned system shouldn't need the 2nd stage. If I ever daisy chain my reactors, the additional stages would be for extra media capacity, not buffering.
