Gold Horizons Rapid Shock

Non-stabilised chlorine granules, ideal for commissioning new spas.

After the commissioning dose is added, leave the pumps running for at least 1 hour and ensure air control valves and water diverter valves are open so that the treated water flows through all the hot tub pipework and jets.

After an hour of filtering, you may want to apply Quick Chlorine Reducer Liquid to speedily lower chlorine levels so you can use your hot tub sooner.
