Pool Chlorine & Sanitisers

Pool Chlorine and Sanitisers NZ

Chlorine is the foundation of a clean, safe swimming pool. Keeping your free chlorine level in the correct range (1 to 3 ppm for most pools) prevents bacteria, algae, and waterborne illness. We stock the full range of pool chlorine products, from fast-dissolving granules to slow-release tablets, all available from NZ stock with fast nationwide delivery.

Crystalline Chlorine Granules (Sodium Di-Chlor)

Sodium Di-Chlor granules dissolve quickly and are suitable for both pools and spas. They are stabilised with cyanuric acid, which helps protect chlorine from UV breakdown. Available in 1kg, 2kg, 4kg, and 10kg sizes to suit any pool volume or budget.

Trichlor Slow-Release Tablets

Trichlor 200g tablets dissolve slowly in a floating dispenser or automatic feeder, providing a steady chlorine dose over several days. A practical choice for pool owners who want to reduce the frequency of manual dosing. Available from 1kg up to 20kg bulk packs.

Pool Stabiliser

Cyanuric acid (stabiliser) protects chlorine from being broken down by UV sunlight. It is particularly important for outdoor pools in sunny climates. Aim to keep stabiliser levels between 30 and 50 ppm for optimal chlorine efficiency.

Choosing the Right Chlorine Product

• Granules vs tablets. Granules act fast and suit shocking or topping up. Tablets release slowly and suit ongoing maintenance.
• Stabilised vs unstabilised. Di-Chlor is stabilised. If your cyanuric acid levels are already high, consider an unstabilised chlorine to avoid over-stabilisation.
• Dosing. Always follow label rates and test your water before and after dosing.
• Saltwater pools. If you have a chlorinator, browse our Swimming Pool Chlorinators range.
