    If you're losing 5 and minimum is 3, take it up to 8.

    It's safe to swim in up to shock level.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!

    My CYA is 60 and I've been adding 5.5 per day, I don't let it get under 7, most often it's 7.5 at night. 7.5+5.5=13 - I add my chlorine between 7:30-9pm. Lately I've been waiting until around 8:30 when the sun is setting.

    Yep, what Richard and Speedo said ^^^^

    I prefer to dose after the sun is off the pool in the evening because the chlorine only has to work on anything organic.

    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.
