    Planning a party. New to SWG

    So I have my pool almost where I want it, but still trying to find the sweet spot for generating FC.

    Right now I'm at:
    FC 7
    CC 0
    Ph 7.6
    TA 90
    CYA 75
    CH 180 (tho with vinyl, I haven't checked it lately)

    If this were still chlorine alone, I'd know what to do, but I'm too new to SWG and don't want to take chances.

    Should I bump up chlorine before "big swim" or do it after? And if so, should I just use bleach to give it a good bump? My SWG has a "Supergenerate" option. Is it better to use that? If so, before or after and for how long? We will have 5-6 kids, and 15 adults although not all adults will swim.

    I wanted to be a help this year instead of a pest, but this is a last minute thing.

    All advice appreciated.

    Yes, bump it up before and check again after. The SWCG is great for maintaining, but use the liquid for these out of the norm situations. Higher bather load means higher chlorine usage. You'd hate that it got below the recommended FC level and then have to fight an algae bloom. This is one of those situations where an ounce of prevention is much cheaper than the cure.
    CYA of 75 never go below 4 with a SWG, Normal Range sis 6-11 Shock is 29 and Mustard Algae Shock is 42. You can swim up to shock levels. Maybe bump it up to 11, and test at the end of the day, and recheck.

    I thought with a CYA between numbers that you would round up, so 75 would be 80? And with a CYA of 80 the target FC level, according to the chlorine/CYA chart, would be 6. Where are you getting a range of 6-11?

    If you use pool math: http://www.troublefreepool.com/calc.html
    There's a suggested FC Levels section towards the bottom.

    And, just FYI, you can turn it down some after the party. You can run in the 4-5 range quite safely

    1 jug of 8.25% bleach adds 4 ppm FC to my pool. I always add a jug before the party and another after the party.

    Ah, didn't scroll down far enough on PoolMath. We are in the same situation with a big party coming up so this is good to know!
