    Help with test results, what am I missing?

    This is our 3rd year opening the pool and did I take good notes from last year? NO!! (what was i thinking? )

    I have a 14x28 inground vinyl pool, 17,600 gallons, sand filter.

    Tests done at 12:30pm today are:

    FC 9
    PH 7.2
    TA 330
    CYA below 20
    CC 0 (my daughter did this test so i didn't see the results but i'm sure she did this right)
    TC 9



    We did the overnight FC test and it was .5 this morning (6am) so we added 2 jugs 182 ounces of bleach. Last night around 6:30pm the FC was 1.5, CC .5 and TC 2.0

    It's clear but green.

    You all helped me last year and I feel like I'm missing "something". I started reading the "Pool School" but again, feel like i'm missing something. Help!!

    Thanks

    Get your CYA up to about 4oppm and you'll hold your chlorine better through the day.

    Stabilizer is easy to raise and difficult to lower. So it is best to add about 2/3rds of the total amount, wait a week, test the level again and adjust from there. Otherwise you risk overshooting and needing to replace water.

    Ok, we're putting in stabilizer.

    Should i also keep checking my FC and keep that at the level required?

    Yes, try not to let the FC dip too far below shock level. Assume your CYA is at the level you are shooting for and adjust the FC level accordingly.
