    Estimating chemicals for extra swimmers

    Good Morning! Do you recommend adding more chlorine than recommended on the chart when more swimmers than normal are expected? We are expecting about 20 or so tomorrow for the 4th and I was just wondering if the target FC is good, or if we should add extra chlorine to account for the extra swimmers...9-10 of those will be kids. Do you also recommend bringing pH down closer to 7.2, since there will be lots of splashing, or do you just leave alone as long as it's within the acceptable range? Most recent test results, just for fun

    FC: 4.5(adding more here in a bit to bump up to 7 for today)
    CC: 0
    pH: 7.5
    TA: 90
    CH: 300
    CYA: 70/75ish

    For a big party I always bring my FC up about 2ppm above the top end of the target.
