    Quick shock question

    It appears the Pool Calculator and the Chlorine/CYA chart recommend different shock levels. i.e. 16 versus 20 for 50 CYA. Which do I use?

    Use poolmath instead of poolcalculator.

    Shock level is 20.

    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!

    Re: Quick shock question is not maintained by its current owner. TFP now has a version (PoolMath) that we maintain and have made updates to some of the parameters.
