    Order of balancing chemicals

    HI All,

    It's been a while since I've posted and I need a reminder on this issue. With the Pool Chemistry listed below, what order should I balance the in? Ex. pH, FC, ALK or FC, pH, ALK, etc.

    FC: 1.52
    TC (CC): 2.73
    PH: 6.8
    ALK: 56
    CYA: 106
    CH: 47

    I have no idea how I arrived at this level of unbalanced chemicals after being away for just two weeks and having a neighbor take care of it for me


    Thanks everyone!

    The first step is a proper test kit

    Define proper? I'm using a LaMotte ColorQ PRO 7.

    I'm not familiar with that test kit, but assuming those numbers are right (FC/CC to 2 places? )

    Half the water needs to be replaced.
    pH needs to come up to at least 7.2.
    FC needs to be closer to 6 (assuming 50% water replacement)
    CH needs to come way up.

    To answer your original question:

    pH
    CYA
    FC
    ALK
    CH

    Your CYA is way too high, probably because you are using tabs to chlorinate. You'll need to lower this to the 30-40 range by draining about 2/3 and refilling with fresh water. Then remove the tabs from your feeder and use only liquid chlorine (aka bleach) to bring your FC into the 3-4 range and add bleach daily so that it never fails below 3.

    If your LaMotte tester is a digital tester, you can search here and find all the reason we advise against those. Here is what we do recommend: Pool School - Test Kits Compared
    25000 gallon free-form gunite
    Jandy Stealth pump/CL340 cartridge filter
    Pentair IC40 SWG
    Pentair MasterTemp 250HD heater
    Jandy AquaLink RS automation
