CA reactor or Dosing?

[GMGQ]

If the water is just streaming out of the reactor, then the pH in the reactor would not be low enough to break down the aragonite. Doesn't the pH have to be around 6.5 in the reactor?

If it's just streaming through the reactor, it would be closer to the level of ur tank, which is around 8.2.
