    rebalance after ascorbic acid treatment

    My numbers are:


    I realize my cya is a little high but would it be a problem since I have a swg and also closing pool in a few weeks. How should I raise the chlorine, I realize its in small increments but where should I start and also should I leave the ta and ph where they are?

    By the way the treatment worked great, the pool looks like it did when it was installed. Very happy, that you so much.

    Re: rebalance after ascorbic acid treatment

    If I follow the drift showed in pool-school/chlorine_cya_chart_shock for SWCG, I'd say aim for 7ppm chlorine, never go below 5.

    TA at 70 seems alright to me, since you're using a SWCG that will raise your pH over time anyway. Having it on the low side will actually help you.
    Thus, pH is alright too, it WILL increase.

    However, when you'll close your pool, if you use pucks to keep it clear until it freezes (which I do not advise with that much CYA already present), raise your pH/alcalinity a bit.
    Pool: None, and All.
