    Shock n Swim ?

    If I ever need to shock my pool again... anything wrong with Shock n Swim? At $2.60 per pound (which is supposed to raise my pool 4ppm), it's cheaper than equivalent bleach (1 gallon of 8% should do the same). I would only use it if I needed to raise FC for shocking. I assume it has a much longer shelf life than liquid.

    It does have a longer shelf life but it's cal-hypo. Every pound will raise your FC by 3.8 and your CH by 2.7. Prolonged usage depends on your CH level.
