    Could someone take a look at my numbers?

    I've got a Circupool SWG, finally got it dialed in. The water is a bit low which I do prior to zeroing in on my final pool balance.

    FC 4.5
    CC 0
    PH 7.4
    TA 70
    CH 330
    CYA 65-70
    Salt 3400
    Borate 80 as near as I can tell. (Strips are old). I'd put this as a maybe.

    This gives me a CSI of -.59.

    My SWG wants CSI between -.10 and +.10, or -.20 and + .20 depending on what you are reading - manual vs data place on box

    Should I kick my TA up a bunch? (store bought baking soda)

    Thanks in advance!
    SWG: CircuPool (5/2018) Universal 40; 3000ppm seems ideal;
    My Ideal Specs:
    FC 5; PH 7.4-7.6; TA 90; CH 350; CYA 75; = SI ~ 0.19

    The lower the Alk, the slower the Ph rise. With a SWG, your water will want to rise. So to keep it at a minimum, I'd leave the Alk as it is. Only thing I'd increase in the Cl level to about 6. The temp of the water will also affect the CSI. My pool is vinyl, I'm sure a plaster pool person will chime in shortly.
