    Pool at New Home Test Results

    I am posting this for a friend who is closing a new home tomorrow with a 16 X 32 in ground pool. The pool has been covered for a year or more.
    It has an aqua troll salt system installed. The pool is only three years old so hopefully everything is in good working order.
    I ran a round of test with my TF-100 Kit this afternoon. (water is clear)

    Chlorine 0
    PH 6.8
    Calcium 70
    Alkalinity 30
    CYA 0
    Salt 1600
    Copper 0

    I can figure out what to do using the pool calculator, but with so many different adjustments is there a specific order?

    Can he do everything at once?

    I was thinking bleach and CYA first, salt next to get generator functioning, and then soda ash for PH.
    Not too concerned with calcium right now (vinyl liner)

    Let me know what you guys think.....

    Sounds like a good order to me!
    If that chlorine reading TC or FC? How does the water look? Shocking the pool might be a good idea too..

    pH first. Because you can't read that during the shock process.
    CYA (but only to 30) next because it takes a while to dissolve. And you'll need some during the process.
    Then bleach.

    Thus far, you've got an hour invested.

    Continue with shock process until the three conditions are met. That could take a few days.

    Then retest. Fine-tune pH and TA and add the rest of the CYA. Remember: you can always add more of something, but removing it is a pain.

    You may have lost some salt from backwashing. Add that. Then start the SWG.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!

    That's Free Chlorine.

    The sample of water he brought me was clear, but he did say there was some "algae" on the walls.

    I'm gonna go by and look at it today because he has never had a pool, Thanks.

    Isn't shocking going to bring the pH up anyways? I was checking this thread: lowering-ph-before-shocking-t25346.html (so I thought shocking before adjusting that low pH would be okay). Is that too low of a starting point?

    This certainly indicates that a shock is in order.
