    TF-100 test kit results...clarification needed??

    Hi Guys,

    I'm new to pool maintenance.
    I have a 30,000 gallon, vinyl lined pool and just performed my first test series.

    The pool was opened and shocked yesterday.

    Free Chlorine measured 20 ppm which I assume is normal while the shock is doing it's job

    TA was 40 ppm. Should I attempt to raise this level at this time?

    Also, I tested for Calcium Hardness since my pool water is very cloudy. CH measured 40. Should I attempt to raise this level, and if so how?

    Step 3 of the CH test states: "NOTE: If the pool water contains copper, add two drops...."

    How do I determine if my pool water contains copper?

    Thanks,

    Pete

    Hey, Pete,

    That's for those that KNOW they have copper. (very few) If you don't know that for a fact, simply assume you don't.

    Yes, you should go ahead and raise the TA.

    Because you have a vinyl pool and don't have a spa you can leave the CH where it is.
