Relax Spa Hot Tub Granular Shock Chlorine – 1kg
Relax Spa Hot Tub Granular Shock Chlorine – 1kg – Rapid dissolving granules for super-chlorination of your hot tub.
Why?Relax Granular Shock Chlorine is highly effective at destroying contaminants (such as bacteria and body oils) 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 Relax Granular Shock Chlorine 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 the shock granules.
6. Water will become temporarily cloudy, keep the circulation/filtration on until water clears.
7. Allow the chlorine level to drop back to 5ppm before using your spa.
5. Ensure your spa is sanitised at all times and test before every use.
How Much?As a general guide, a heaped tea spoon holds 8g of granules.
Spa Volume 1000litres – 15g
Spa Volume 1500litres – 22g
Spa Volume 2000litres – 30g
