Thread: So everything was going good and now...

    So everything was going good and now...

    So thanks to all the usefull info on here I was able to recover the water from a black/green lagoon to crystal clear pool. Everything was good and then algae started to creep in. i was able to get rid of it following SLAM and now i'm still left with cloudy water. The system has 4 cartridge filters that were replaced earlier this week (not sure if that changes anything). and right before the cloudiness I decided to raise the CYA because it was staying down around 20 so could that have anything to do with it? my readings at the moment are
    FC- 11.5
    CC- 0.5
    TA- 70
    CH- 220
    CYA- 35-40
    ph- 7.5

    Will continuing with SLAM clear the cloudiness? and then is there anyway to prevent it from happening again?
    On a side note... I know it varies pool to pool but how often/much should bleach be getting added? I felt like I was having to add quite a bit everyday for a while to keep the chlorine levels up?
    ~12k gal in-ground plaster, the pressure on the filter stays around 10psi, 1hp pump motor. waterfall, spa that overflows into main pool. hayward cartridge filter still learning the rest. (if you can help msg me lol)

    Your CYA level could have been anything below 20, and it's certainly possible you were losing most of it to sunlight. Do you have a record of your tests you can review? Did you ever let your FC get below your min for your CYA level?

    Yeah i did run out of bleach so i went a day or two with fc dropping at which point i threw in trichlor tab into the autofeed.

    Forgive me, maybe I am misunderstanding the OP: I am a Newbie too, but in my understanding you can't finish a SLAM with cloudy water. The conditions are: clear water, FC = 0 and pass OCLT
    1) 21,000 gallons
    2) DE
    3) IG (in ground)
    4) Vinyl
    5) Hayward 1.5 hp DE 3600 72 GPM

    This is correct.

    Not quite correct.......FC=0?? I think that should be CC=0.

    Just in the interest of precision I believe its CC of 0.5 or lower.

    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.
