    reccomendation to balance salt water pool

    CYA: 90
    FC: 7.5
    PH: 7.6
    CC: .5
    TA: 200
    CH: 725

    Tested with Taylor K2006.

    I just went up to my moms house for the weekend. She has a pool man that does her pool.
    I brought my test kit to see how good he is doing.

    I am curious are these numbers bad for a saltwater gunite / plaster pool with salt water generation?
    CH seems really high.

    What would y'all do to balance.

    I think maybe lower CH to 400 and TA to about 90?

    What will high CH do to plaster?

    The only way to lower it is by draining some water and refill with lower CH. The CYA is a bit on the high side too. I don't know exactly what the fill water test like, but my guess is the pool would benefit from a drain and refill of about 20%. That would lower the CYA to about 70 and hopefully bring the CH down to a more reasonable number. The TA is also very high, and my guess, since it's a SWG pool is its difficult to keep the pH from getting too high, which if not controlled would cause scale.

    I have a SWG pool; 20 K gallons, in ground, gunite. Where I keep it:

    FC - 1 to 5 ppm
    pH - 7.4 to 7.6, no higher than 7.8
    CH - 175 - 400 ppm
    TA - 80 - 120 ppm
    TAc - 50 - 80 ppm
    CYA - 70 - 80 ppm
    Salt - 3000 - 3500 ppm

    My pool is in it's third season, it has never been out of LSI balance.

    I assume you mean CSI not LSI. You need to raise your FC target. With a CYA in the 70 your FC range should be 3 to 5, and with CYA of 80 it should be 4 to 6.

    So we swam in my moms pool with the results posted above. Had some skin irritation and burning ing of the eyes. a little late but was it safe to swim technically.

    The CH is high. Given hard water and probably a lot of evaporation where she is, I'm not at all surprised.

    If you plug those numbers into poolmath and change things around, you will see that lowering the TA is the easiest way to lower the CSI.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!
