HTH Premium Chlorine Shock is a fast-acting calcium hypochlorite-based shock treatment for swimming pools, supplied in a 5kg pack. Shock dosing is an essential part of any pool maintenance routine, used to rapidly raise free chlorine levels, break down chloramines, eliminate algae, and restore water clarity following heavy use or periods of warm weather.
This high-strength formula acts quickly upon addition to pool water, making it effective for reactive treatment when water quality deteriorates, as well as for planned weekly or fortnightly shock dosing as part of a regular maintenance schedule. The fast-dissolving granules distribute evenly through the pool, allowing a return to normal use as soon as chlorine levels return to the recommended range.
Key features:
Always test pool water before and after shock dosing. Shock at dusk or after bathers have left, and do not allow swimming until chlorine levels have returned to 1 to 3 ppm. Wear appropriate PPE when handling pool chemicals.
