    add Calcium before or after Borates?

    I would like to add Borates to my pool, but my CSI is registering at -.63, would it be better to add calcium before or after Evan's "So you want to add borates to your pool..." method. Or, should I not even worry about the CSI until after all that...

    here are my latest figures,

    FC 5
    PH 7.4
    TA 80
    CH 110
    CYA 70
    Salt (I don't test, must be at least 50 by now due to adding bleach)
    Borates 0
    Temp 76
    CSI -.63

    Thanks! Happy 4th!

    You have a vinyl pool. Don't worry that much about the CH or CSI. 110 should be fine. (Although I personally recommend a CH of around 130 or higher for vinyl).
