Pure-Spa - Spa Chlorine Shock Granules - 1kg or 5kg
Calcium hypochlorite (avg 70% Cl active)

Rapid Dissolving Chlorine Shock Granules are an unstabilised chlorine shock product ideal for raising Chlorine readings without having an impact on stabiliser readings (cyanuric acid).
Ideal for Shock Dosing swimming pool or spa water on a weekly basis or after heavy bathing.

WHY? Chlorine  Granular Shock is highly effective at destroying contaminants (such as bacteria and body oil) from your spa water.

WHEN? Shock or ‘Super’ chlorination is necessary when first filling or re-opening your spa. It is also good practice to ‘Shock Treat’ your spa water every 2 weeks or more often if your spa is heavily used.

HOW? 
1. Pre-dissolve the required amount of Chlorine Granular Shock in a clean, plastic bucket filled with warm water. Stir the solution until the granules are fully dissolved.
2. Ensure that your spa circulation pump is turned on before slowly pouring the solution directly onto the spa water surface.
3. Continue to run your spa circulation pump for at least 1 hour.
4. Repeat treatment if necessary to reach a Chlorine level of between 10ppm & 15ppm.
5. Leave spa cover off for 2 hours immediately after adding Chlorine Granular Shock.
6. Water will become temporarily cloudy, keep the circulation/filtration on until water clears.
7. Allow the Chlorine level to drop to 5ppm before using your spa.
