    Adding chlorine for maintenance

    I just did a 50% water change and am start the TFPC method.

    My numbers this morning using the Taylor kit
    FC 4
    TA 100
    pH 7.5
    CH 260 but I have really hard water
    CYA 40
    CC 0

    According to the pool calculator I am good where it is.

    I have read the slamming page and understand that slamming is done when algae is present, FC is 0, or CC is above or 0.5. What I can't find is how to add chlorine to maintain the FC level. I am using 12% liquid chlorine. Do I just add a little chlorine each day and see how much it takes to maintain FC in the 3-7 range recommended by the pool calculator given my CYA?

    You should target 6-7ppm each day. Just slowly pour the amount that PoolMath calculates to hit that target in front of the return jet each day.

    So test the FC each day and use the amount shown to raise it as needed? From there I should be able to start testing less often?

    Yes. Test the FC level, enter that in the now column. Confirm the target column is what you want and add that amount of bleach.

    You likely need to be testing daily, then maybe every other day once you know the pool.
