    First Test = bad...

    FC= 0
    CC= 0
    PH=7.8
    TA=60
    CH = 260 (I don't believe this is actually accurate.. it went from pink to more of a purple instead of red to a blue ran the test twice)
    CYA = 0 (Ran the test three times with two different samples... The black dot started getting foggy at 20 but you could still it at the top of the vial)

    Going to start by adding 2 gallons of bleach. I'll also buy some Baking soda while I'm out today but am hoping for some advice before I add it..


    pool is 26000 according to the guy I had come out and quote me a plaster job.

    Why are you buying baking soda? You don't need to raise your TA. You may never need to. You need bleach and CYA.

    For the CH, see the extended test instructions here on how to deal with the purple: extended-test-kit-directions-t25081.html

    You DO NOT need Baking Soda.

    Read "The ABC's of Pool Water Chemistry" up in Pool School.

    Using PoolMath, purchase enough CYA to get to 40 ppm. Test a week later.

    Next, add the chlorine. 2 gallons is a bit much....put in 1.5.

    What does your water look like? Where do you live?

    In that case, you could add enough baking soda to get up around 90 or so but that doesn't have the priority that chlorine and CYA do.

    +1 to what Duraleigh just posted. The chlorine and stabilizer need to go in soon. Everything else can wait.
