Thread: Bacteria after shock

  1. Back To Top    #1

    Bacteria after shock

    25,600 gallon, vinyl liner above ground
    Ch 7.5 after shocking to 16 after opening
    Ph 7.8.
    Alk 80
    Cal 210
    Cya 45
    Bor 50
    Temp 81
    After testing the ch at 7.5, the secondary testing turned faint pink and cleared with one drop. Should I top out the bleach to 16 again or am I ok with a little more time.

    Forever in your debt,

    Sharon Maxwell

    I think there is a typo. Do you mean FC? or TC?

    Anyway, we need to see the FC and CC test results.

    ETA: ....and how does your water look? crystal clear?

    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.

    All is well with my pool. I did not lose any FC last night, still at 7.6 ppm and the CC has dropped to .2 ppm.

    I would like to state that after one season using troublefreepools.com, I have experienced the easiest opening in eight years. The only expenses I have had this year are replacing broken cleaning tools and lots of beach of course.

    Thank you.
