    Struggling to Get Clear Water

    I have been reading this site for just over a week and started by ordering the TF-100 test kit.
    Below are the results
    FC 1
    CC .5
    TC 1.5
    ph 7.8
    T/A 170
    CH 240
    CYA Did not measure so somewhere below 20

    Pool is cloudy and will not hold Chlorine.
    Based on what I have learned by reading this great site I see two issues with my results but not sure where to start.

    I need to Lower T/A and increase CYA but not sure where to start.
    Any help would be greatly appreciated.

    I'm new here too but had the same issue as you a couple weeks ago. Start shocking ASAP till it clears up then worry about TA and CYA. It's easier to shock with low CYA and your TA levels probably won't affect the cloudiness. Get some liquid chlorine or bleach and go to it. If anything like mine, it will be crystal clear in a few days. Just be anal in checking chlorine levels and adding bleach as often as you can.... Especially at night!

    Adjust CYA to 30 and begin the shock process as described below

    pool-school/shocking_your_pool

    Too much CYA (90+) makes shocking a dificult process. CYA at 30 lets you shock at a reasonable FC level (12 or so ppm to reach shock) yet sheild it from UV rays to avoid burning it off to quickly. As mentioned above, raising your FC to shock level in the evening is especially helpful as it will go to work against organics rather than also fighting of chlorine lost to sun exposure.

    I starting shocking the pool last week and it seems to hold pretty good overnight but as soon as the sun comes up it is gone. So should I adjust CYA first so I don't loose so much Bleach?

    Yes, go ahead and add enough CYA to reach 30 ppm. That will help the chlorine last a little longer while you shock.

    Don't forget to scrub the pool walls and floor a lot! Even use a hand brush to scrub around lights, stairs, returns, etc....

    The next time your FC drops below 10, retest your pH and lower it to 7.2.

    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.
