Saw this study done by BRS. Very interesting. I have observed this as well. I think the "tribal knowledge" is that a secondary chamber on your CARX will result in significantly higher effluent pH and effluent strength. It appears that the facts are that the pH is only very modestly increased, as is the effluent strength. So it may not be worth the money/complexity to run a secondary chamber.
BRS CARX Secondary Chamber Study
Might save some folks some money initially setting up a calcium reactor, and time trying to improve your pH since this method is unlike to move the needle much.
