- Product Description
- Specifications
Our 5kg stabilised chlorine granules provide a reliable way to maintain safe, hygienic water in your hot tub or swim spa. Designed for regular sanitising, this granular chlorine works as a powerful hot tub sanitiser, helping control harmful bacteria, algae, and organic contaminants.
This larger 5kg tub is ideal for frequent spa owners, holiday let properties, or anyone maintaining water over longer periods. Keeping chlorine levels between 2-3 ppm helps maintain proper sanitation, strong water quality, and excellent water clarity for a comfortable hot tub experience.
For best results, pre-dissolve the granules in a separate clean bucket of water before adding them to your hot tub while the circulation system is running. Pairing chlorine granules with our 3 Way Test Strips helps you monitor your water chemistry and maintain proper levels for safe and enjoyable hot tub use.
With fast dissolving performance and dependable results, chlorine granules are one of the most popular sanitisers for everyday hot tub care. Regular testing and maintenance also help prevent cloudy water and keep your spa ready whenever you want to relax.

Safety tips
Never mix chlorine granules with other chemicals. Always add granules to water, never water to granules, and wash your hands after handling.
When to use
Use regularly to maintain chlorine levels between 2–3 ppm. This supports proper sanitation and keeps water clear, safe, and comfortable for spa users.
How much to add
Adjust the amount based on the size of your hot tub, usage, and current chlorine level. Test strips help you maintain proper levels easily.
Pre-dissolving
Mix granules in a clean plastic bucket of spa water before adding to your hot tub. This helps the sanitizer spread evenly and protects your spa surfaces.
Why Use Chlorine Granules?
Chlorine granules provide a simple and effective way to maintain safe water in your spa. They support balanced hot tub chemistry, prevent harmful bacteria, and help keep water clear, fresh, and ready whenever you want to enjoy your hot tub.
