1kg Superfast Shock Granules (Calcium Hypochlorite 75% available) (was Fi Clor but now rebranded under the name HTH)
HTH shock granules contain approximately 15% more available chlorine than standard calcium hypochlorite meaning you use less per dose.
Formulated to destroy algae, Superfast Shock can also be used to boost chlorine levels quickly when using stabilised granules or tablets as your regular maintenance chlorine. Perfect to give the pool an initial dose of chlorine when opening in summer or to keep pool clear during winter closure
Suitable for Above Ground Pools and In Ground Pools
