    You can use PoolMath to figure that out. Look at the effects of adding chemicals section towards the bottom. Typical trichlor tablets are 7 oz. It takes quite a while to raise CYA with trichlor.

    Those pucks are 7 oz each. Your pool is 6981 gallons, according to intex. Looking at Effects of Adding Chemicals in Poolmath, each puck will raise FC by 6.9, raise CYA by 4.2, and lower pH by .37.

    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!
