Multi-Functional Shock Chlorine For Swimming Pools
H2oFun's Multi-Functional Shock Chlorine is a fast acting, powerful, swimming pool shock treatment with the addition of a water clarifier. Formulated to destroy Algae and restore swimming pool water clarity it should be used once a fortnight or more frequently during hot weather or when the pool is used more often
300g of Multi-Function Chlorine Shock will treat a 10ft x 20ft swimming pool, containing 20,000 litres (4,500 gallons) or if Algae is present in the swimming pool it is suggested to double the dose. To close your swimming pool for winter we would recommend using it the day before adding any algaecide.
After using Multifunctional Chlorine Shock in your swimming pool ensure that the chlorine level has dropped below 3ppm before using the swimming pool, this figure can easily tested using Aquachek Test Strips.
Always test your swimming pool water before bathers enter the pool after using any chlorine shock treatment
