    First pool opening, here are my numbers

    I just put in my inground vinyl lined 29K gal salt water pool last year. I did hire someone to close the pool before winter, but I would like to open it up myself. I have read the "opening a pool" newletter from trouble free pools, but the local pool place is guiding me in a different direction. Help would be appreciated.

    Tested results from pool store....

    Total Chlorine 5.5
    Free Chlorine 5.2
    TDS: 1900
    PH: 7
    Tot. Alk 111
    Adj Total Alk 102
    Tot Hardness 92
    salt 1400
    borates 0

    Pool store told me not to shock the pool because my Chlorine levels were already high from last session. Is this correct?

    They also told me not to put algie preventer in because my salt generator would take care of it?

    The results tell me I should raise my PH. What about Tot Hardness and anything else.

    Help is always appreciated....

    A couple more points. I haven't cycled the water yet. The pool is located in cold Boise, Idaho. I have an automatic pool cover and dry chlorine was dumped in to winterize.

    Not sure how my chlorine levels could stay so high for 6 months without adding anything??

    It looks to me like you need salt.

    If the test results are right the SWG can take care of everything else.

    Yes, chlorine can survive the winter if you do everything right.

    So I shouldn't adjust anything before adding salt?

    Is there harm in that my total and free chlorine are not the same?

    Should I aerate the pool first to bring up the PH and lower alkalinity?

    Should hardness be much higher?

    BigDave,

    Welcome to the forum. All those stupid nopes were my way of saying Jason's got you covered. Your numbers are decent and the SWG will correct the minors variances you do have.

    We almost never consider TDS on this forum but a Calcium Hardness test might be helpful when you get a chance.

    Thanks Jasonlion and Dave!

    Being new to the pool chemical scene is a learning process. But you guys are bringing me up to speed fast.

    The forum has helped me out a few time now since building my own pool last summer, and boy that was a job. I hired out only the excavation, auto pool cover, and finished cement. The poolcrete about killed me, lost 15lbs and my forearms look like popeye the sailor. Not sure where to upload a pic or I would. Pretty proud of my completed job.

    Forgot to add my CYA is 30. I will check my CH when I get a chance.

    When is the best time to bring up my borates? After I get the system up and stable with good chem readings? I did read the sticky on borax and acid and it was very well documented, awesome work....

    You should bring CYA up to between 60 and 80.

    Wait on borates till TA is lower and everything is stable.

    You're done SLAMing when:
    1)You lose 1ppm or less FC overnight, & 2)You have .5ppm CC's or less, & 3)your water is clear.
