Spa Non Chlorine Shock

Spa Non Chlorine Shock is a granular product that is ideal for regular oxidation of your spa water which does not increase chlorine or bromine levels, bathing can resume shortly after application.

Regularly oxidising pool water, ideally weekly, will pay dividends in the prevention of spa water problems. Non-Chlorine Shock dissolves rapidly to break down unpleasant pollutants and organic matter and is effective over a wide range of water conditions and pH values.

Can also be used for reactivating spent Bromine in Bromine treated Spas.
