I believe according to directions of the MRC dual chamber Ca reactor that 2nd stage effluent will be .3-.5 pH units greater than the 1st chamber. So it sounds like you are OK.

One suggestion...get a pH controller...put the probe in the 1st chamber and regulate to your desired pH ~6.5-6.6. Then follow the online Ca setup calculator in the chemistry forum.
