Non-Chlorine Shock Granules from Yourspa (1kg)

Break down waste, odour and cloudy water with Yourspa's Hot Tub Non-Chlorine Shock granules.

What is shock treatment?

Shocking a hot tub spa is the application of an ample dose of chlorine (sodium dichlor) or non-chlorine shock (potassium monopersulfate or MPS). One purpose of this treatment is to break-down organic waste contaminants which cause odor and cloudy water. After treatment, water quality and clarity is often completely restored.

If irritating chloramines are present, shocking also converts them back to active chlorine. If bromine sanitizer is being used, shocking activates the bromide ion (which by itself has no disinfecting capability) which becomes hypobromous acid in water, a good sanitizer. Both of these shocking products are 100% compatible with the alternative sanitizer systems that we offer.

Regardless of which sanitizer system you use, periodic shocking is essential for clear, clean hot tub water. It will also allow your sanitizer to perform at peak efficiency:

  • Restores water sparkle
  • Destroys swimmer waste

How to apply this Hot Tub Non-Chlorine Shock:

1. Maintain pH levels within the ideal range 7.2 – 7.6. If the level is not in this range, adjust.

2. Maintain free chlorine levels in the range pools: 1 – 3mg/l (ppm); spas 3 - 5mg/l (ppm). Maintain bromine levels in the range pools/spas: 3 – 5mg/l (ppm).

3. Pre-dissolve this product in a clean plastic container at a maximum rate of 100g of product of 2.2 gallon (10 litres) in water. Stir well to ensure product is fully dissolved. Add the resulting solution to the pool or spa whilst the pump (s) are turned ‘on' preferably near the water inlets to aid distribution.

4. After shock treatment procedure, allow at least 30 minutes before bathing recommences.
