Chlorine granules are a simple and effective way to keep your hot tub or swim spa water clean and hygienic. These stabilised granules dissolve quickly, releasing free chlorine that kills bacteria, algae, and other contaminants.
Ideal for daily sanitising, they are perfect for spas without automatic chemical systems or for homeowners who prefer hands-on water care. Paired with our 3 Way Test Strips, you can easily check chlorine levels and add granules only when needed.
Chlorine granules are safe, easy to use and have minimal impact on pH levels. With a little regular care, you’ll maintain clear, fresh water and enjoy your spa with confidence.

Safety tips
Never mix with other chemicals. Always add granules to a clean bucket of water first, don’t add water to granules. Store the pot in a cool, dry place away from dampness and wash your hands thoroughly after handling.
When to use
Use daily or as needed to maintain chlorine levels between 2-3 ppm, especially in spas without automatic chemical systems.
How much to add
Increase free chlorine by about 1 ppm per 1000 L of water (~2 g granules). Adjust based on spa size, current levels, and usage, guided by test strips.
Pre-dissolving
Mix granules in a clean plastic bucket of spa water before adding to ensure even distribution and avoid direct contact with the spa surface.
Why Use Chlorine Granules?
Chlorine granules make maintaining your hot tub water simple and effective. They help keep your spa safe, clear, and fresh, preventing bacteria and algae build-up. When paired with test strips, maintaining the right chlorine level is quick and worry-free.
