    How are these numbers? Any suggestions?

    I am just coming off a SLAM. Pool is crystal clear. Should I be concerned with the High Alkalinity? I was going to add a little chlorine to keep it a bit higher with the CC of 0.5. Any other suggestions?

    FC 9
    CC 0.5
    pH 7.6
    TA 120
    CH 400
    CYA 70
    Temp 74

    Short answer: no.

    When the pH rises to 7.8, add acid to get it down to 7.2. That'll shave 10 points off the TA right there. It'll come down over time as long as you maintain pH. There's no point in getting aggressive with it.

    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!
