Granular Chlorine: The Ideal Sanitiser for Clean and Balanced Pool Water

Looking for a reliable way to keep your pool water clean and safe? Granular chlorine is a highly effective solution for Australian pool owners. With strong disinfecting properties, it kills bacteria, controls algae, and maintains water balance.

At Hy-Clor, our premium granular chlorine products are easy to use, fast-acting, and perfect for daily maintenance or shock treatments. Whether you’re topping up chlorine levels or deep cleaning, granular chlorine delivers the performance you need.

What Is Granular Chlorine?

Granular chlorine is a concentrated pool sanitiser, typically made from calcium hypochlorite (non-stabilised) or Sodium Dichloroisocyanurate Dihydrate (stabilised). It’s available in dry, granulated form, making it easier to store and apply.

Once added to water, it dissolves quickly and releases free chlorine, which targets and eliminates harmful bacteria and other contaminants. This makes granular chlorine an effective choice for keeping your pool clean and clear.

Benefits of Using Granular Chlorine for Pools

Granular chlorine offers several practical advantages:

  • Effective Sanitising
    Rapidly eliminates bacteria and algae for safer swimming conditions.

  • Versatile Application
    Can be used for routine chlorination or as a shock treatment when needed. Please note, do not use a stabilised chlorine for shock treatment. Only use non stabilised granular chlorine or liquid chlorine for shock treatment.

  • Cost-Effective
    A budget-friendly way to maintain crystal-clear water without sacrificing quality.

How to Use Granular Chlorine in Your Pool

Follow these steps to safely and effectively apply granular chlorine:

1. Calculate the dosage

Always refer to the product guidelines before proceeding. Take into account the size of your pool and its current condition (e.g., cloudy or clear water). For routine maintenance, the typical dosage is around 40-80ml per 10,000 litres of water. Double-check the instructions on your specific product for accurate measurements.

2. Pre-dissolve

To prevent staining or uneven distribution, dissolve the required amount of product in a clean bucket of water. Stir well to ensure it’s properly mixed before adding it to the pool.

3. Apply evenly

With the pool filter running to ensure proper circulation, pour the solution evenly around the edges of the pool. This helps distribute the product effectively, ensuring your water stays clean and balanced.

Safety Tips

  • Always wear gloves and protective eyewear
  • Never mix with other chemicals
  • Store in a dry, cool, well-ventilated space away from sunlight and moisture
