    New to pool word. First fill numbers. Hellp appriceated.

    Ok folks,
    Newbie into the pool world. Have an Intex Easy Set 18ftx48in round. After filling it yesterday and adding chemicals last night here are my numbers this moring using the Taylor K-2006 testing kit. The pool is in full sun most of the day. So without any CYA I am worried about FC loss.

    FC 7.5
    PH 7.6
    TA 170
    CC .5
    CYA 0

    I have on hand Bleach, Borax, Baking Soda, and Dichlor (as my stabilizer???) Pool Math shows that I need to add 3.5 oz of Muratic Acid and 30oz of Stabilizer.

    Two questions that I have.... 1. Can I use Dichlor as my stabilizer? 2. Should I wait to add the MA until after I get the CYA up to 40 or so?

    Thanks for your help!

    Welcome to TFP!

    PH at 7.6 is perfect, no MA needed

    Yes, it is fine to use dichlor to raise FC and CYA. It will just take longer so be sure to check FC later in the day to make sure it stays above minimum for your CYA, FC/CYA Chart

    Thanks,
    I just added 1.8 pounds of Dichlor by using a white sock and floating it in front of my return jet. Took aobut 10 min to discipate. I will recheck FC levels later today. Is the TA at 170 a problem?

    Thanks!

    Depends on what your pH does. If it rises quickly, acid will lower both.

    you can use the dichlor to bring the CYA up, it is slower than using 100% CYA but it will do the following

    Add free chlorine
    add CYA
    drop PH

    6 ounces of dichlor for 7600 gal pool will

    raise your FC 3.3
    add 3 CYA
    drop PH 0.12

    Your FC will go very fast at first until your CYA gets at about 30

    Once your CYA is at 30 start using bleach instead

    congrats on the new pool and test kit, great job

    Thanks for the information. The kids have been in the pool today. No complaints about the water. The last 8 tested FC was high at 13.5 and CYA was starting cloud up on the tester. Not quite where it needs to be. I will test again be for i turn in.

    With little CYA, FC=13.5 is at SLAM levels. Might be a tad high for safe swimming. Perhaps more experienced TFPers could weigh in...

    It is safe to swim when FC is above minimum and below shock level for your CYA, FC/CYA Chart
