Poolgard Shock N Swim
Used in conjunction with daily chlorine, shock N swim is used in place of "shock chlorine" to burn out the build-up of impurities in pool water. This keeps water nice and clear and also makes chlorine more effective as chlorine's primary purpose becomes that of a sanitizer.
Recommended Usage: add fortnightly to the pool at the rate of approx. 750g per 45,000L pool.
