    Calcium Reactor pH Range

    I've been having problems with my calcium reactor pH range was driving me crazy it was overshooting the high and low setpoints until I found out my recirculation pump on GEO 618 was not working. Now my question is I'm still getting carry over above/below my setpoint of 6.9-6.8 It's very minimal it will carry above or below to 7.0 abd 6.7 (+/- 0.1 difference) I can understand if it's carryover meaning I'm adding too much C02 so it will go below 6.8 setpoint but doesn't make sense on the high side going above 6.9 since I'm supposedly adding too much co2? the chart is showing a tight consistent buzzsaw graph so maybe I should just leave this as acceptable?

    It's not overshooting, that's actually what you programmed it to do. It has to go above or below your set points to turn on or off, not on them.
