    Still can't get it right

    I was getting really high CYA levels and I replaced at least 1/2 of my pool's water with new. I let that circulate for 24 hours and here are the new results

    pH 7.2
    FC 4
    CC 0
    CH 250
    TA 150
    CYA 70
    16x32 (22K gal)/ IG/ vinyl liner/Hayword Proseries Sand filter

    Do you have a SWG? If so your CYA is fine. Your FC is too low for 70 CYA though. FC/CYA Chart

    If not.... your CYA must have been about 140ish to start.

    How's the water looking? How are you testing?

    how high was really high? Was it over 100? What test/test kit got you a reading over 100? If your CYA was 140-160, then you would expect to be at 70 after a 1/2 drain.

    Your FC is still a touch low, but all your numbers are within usable range, just some tweaking but nothing bad.

    You may be fine to just let it ride if you get a lot of rain. Get the FC up.
    I'd bet you my bikini you'll never get TFP water from a pool store!
