CA reactor or Dosing?

[GMGQ]

Hmm, so basically you would let the reactor flood with CO2 until the pH is too low, then your pH controller would shut off the CO2, and the reactor would slowly fill back up with regular pH water, then the controller would restart the flow of CO2?

What CA level do you maintain?

This has worked really well for me. The controller keeps the ph in the reactor stable. I used to try to dial in the "bubbles per second" years ago, but I just ended up letting the controller do the work and that's the best thing that I've done with the whole reactor set up. Hope this helps.
