    How soon after adding clorine

    Can you check to get a gauge of where you really are ppm wise
    1) The size of your pool in gallons = 33,500 16x32x40 L
    2) The type filter you have = 300lb Sand
    3) IG
    4) If it's IG, vinyl liner
    5) pump is 1.5hp

    It really depends on your pool but most folks here say 30 minutes to an hour after adding Chlorine. I wait an hour even though I have excellent movement in the pool.

    I used to think 30 minutes was enough but, on another thread, OP reported a ppm of X in 30 minutes and in 30 minutes more (one hour total) reported another 1 or 2ppm rise.

    All pools will be different but one hour now seems safer to me.
