Thread: getting ready to start the Autopilot

    getting ready to start the Autopilot

    We got the manifold all plumbed in last night, and we're getting ready to power up the Autopilot.

    Here are my numbers:
    FC 3
    ph 7.2
    alk 90
    cya 40
    salt 3500

    I'm going to raise my cya to about 70, but my real concern is with the low ph. After getting the alk down to 90 (from 120) using acid and aeration, I can't get the ph to budge any higher than 7.2 (after 4 days aeration--fountains & returns only.)
    Is 7.2 acceptable to start the Autopilot or should I add Borax to tweak the ph higher? I know the target is 7.5, but won't the ph creep up when the Autopilot starts producing chlorine?

    It should rise once the SWG is operating. I'd leave it alone for now, won't hurt anything. Get that CYA up though.

    Good luck!

    PH at 7.2 is acceptable for swimming and the AutoPilot. Once the SWG is running, the PH will probably start drifting up slowly and get up to a better level, so no need to adjust it right now.
