    tested with tf 100

    new semi in-ground vinyl pool 15x24, 54"deep, 13,350 gal. started out with pool store advice, until i found this forum which i'm very grateful for. the pool store advice was setting me up for a CYA saturation, thanks to this forum i was able stop before it got real bad. these are the results form the tf 100, pool school recommend CYA 30-50 except in extreme sunlight, what is considered extreme sunlight? how many hours of sun?

    fc 9
    cc 0
    ta 120
    ca 240
    ph 7.3-7.4
    cya 65-70 would have been worse if not for this forum thank you all, i love liquid bleach wal mart 8% 3 bucks a gal.

    Welcome to TFP. You've come to the right place.

    Don't add any more stabilizer. Don't use the pucks.

    Everything else looks good. CYA a tad high. With 65-70 ppm of CYA don't let your min FC level drop below 5 ppm. 5-9 5-10 ppm is your range.

    How much sun do you get ? Also put your pool info in your sig. It will help us help you.

    If you keep on top of your chlorine and never let it drop below the minimum, you will be fine. If you ever run into a problem, you can worry about your CYA then. Test daily, and always add enough chlorine to stay above min, and you will be good.

    About the same for my pool.

    50 ppm for CYA seems about right for me. You can manage that 65-70 that you have.........I'd probably allow it to come down naturally over time, though.
