Use Spa Non Chlorine Oxy-Shock on a weekly basis or after heavy use of the Spa or Hot Tub. This product will break down the organic contaminants and un-filterable waste sometimes found in the water which can result in unpleasant smells/odours and a reduction in bather comfort.
Spa Non Chlorine Oxy-Shock can also improve the efficiency of the Bromine sanitiser.
