    Pool Just opened

    I have a friend who just opened their pool. Vinyl 14000 gallons

    FC 0
    TC 0
    PH 6.8
    TA 20
    Calcium Hardness 200
    TDS 400
    CYA 0
    Water is cloudy.

    trying to put my limited knowledge to work here since joining TFP. Should she start by getting the CYA up. Until that happens the chlorine will just not hold at all. Than shock to get FC up and eliminate CC if there ... than balance PH and TA?

    Start with TA; get it up to maybe 80. That will help get pH in line too. Once TA and pH are in range, you can start shocking and add CYA at the same time.

    i dont think there is a specific order. i would add the propper amount of cya first since it could take a few days for it to disolve. from this site ive heard that chlorine works the best when the Ph is in propper range. since the Alk. buffers the Ph i would get the Alk. in order first. Then get the Ph to around 7.5.. now i would bring the chlorine up to shock level. kepp it there until you do an "overnight free chlorine loss test". test the FC level b/f you go to sleep and when you wake up test again. if u lost more than 1ppm then u need to keep shocking... this sounds like a start to me!

    Yep, I agree. Adjust TA & pH first. Then add CYA and start shocking at the same time.

    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.
