    My kalk stirrer hasn't been running for close on a month and my pH is more stable than ever, night time pH drops to 8.1, daytime is 8.3.

    When it was running it was swinging between 7.9 - 8.4.

    Alk is stable at 8.

    CARX pH is set at 6.3 with about 3 drops a second, and is always turned off at night.

    Howcome? Does anyone else have similar readings?

    My Ph is 8.3 during the day and 8.2 at night. I don't know why it is so stable because I only run a calcium reactor (Runs all the time) and I don't have any reverse lit fuge.

    Are managing with your alk and calcium? I know the CARX supplies most of it but the kalkstirrer does help keep it up there.

    Probably has something to do with your carbon dosing (which drops Ph) or your Alk levels which also effect Ph.
    Now at the same time, we were in winter and most of our windows and doors were closed because of the cold thus increasing Co2 level in the house, thus dropping the Ph. Could it have happened with in this time frame (winter)?
