Stabilised Chlorine Granules 5KG


Product Description

Your choice of sanitiser for your Hot Tub, Spa or Pool is important, as it's the main defence against viruses, bacteria and infections in the water. Stabilised Chlorine Granules are an excellent choice, as they're almost pH neutral, allowing you to dose without adversely affecting water pH.

Usage Information

The ideal chlorine reading in your water is between 3 and 5 ppm, which can be tested using Aquachek test strips. If the reading is too low, you'll need to add more Chlorine Granules to your water. Go easy, and don't overdose the water, as it is far easier to fix an underdosing than an overdose.

The impact of pH on efficiency of Chlorine Granules
Your Hot Tub or Pool pH value has a direct impact on the ability of the Chlorine Granules to sanitise the water. In general, a high pH means Chlorine isn't as efficient as with a low water pH.

  • Water pH of 6.5 - Chlorine is around 90% efficient
  • Water pH of 7.0 - Chlorine is around 75% efficient
  • Water pH of 7.5 - Chlorine is around 47% efficient
  • Water pH of 8.0 - Chlorine is around 22% efficient

Overdosing Information

We strongly advise you to take care, and avoid overdosing if at all possible. If you have, unfortunately, added too large a quantity of Chlorine Granules, leave the cover off of your Hot Tub, Spa or Pool, and turn on all of the pumps, which will encourage some of the Chlorine to evaporate away naturally. In severe cases, a Chlorine neutraliser will need to be added in very small amounts. The worst thing you can do, contrary to popular anecdote, is add any pollutants to the water to help encourage burning off of the Chlorine.
