    For a SWG, use 4. That's the minimum FC. If you drop below that, crank the SWG up a notch. Personally, I'd target something like 6, since it builds in a cushion in case you have a sudden demand on the chlorine. It takes a SWG a few hours to build up the levels, whereas with a jug, it's just seconds.

    The last box on poolmath will let you set up targets. Choose SWG and it will set it up for you in the rows above.

    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!
