  • Our chlorine granules are manufactured with a stabilising agent to help prevent the destabilisation and destruction of the chlorine by sunlight and UV rays. This prolongs their usefulness as a sanitiser over other types of non-stabilised chlorine and makes them ideal for use in swimming pools, spas and hot tubs whether located indoor or outdoor. These chlorine granules should be routinely used to help maintain a safe bathing environment.
  • Swimming Pools: Routinely use between 2-3ppm residual chlorine in small or domestic pools and 3-5ppm in public or heavily used pools. For each ppm of chlorine increase required use 40g per 25,000 Litres of water.

Frequently Asked Questions

AI
Granules are ideal for 'shocking' a pool or rapid disinfection, while tablets provide a steady, slow-release dose of chlorine for long-term maintenance.
Stabilised chlorine contains cyanuric acid, which protects the chlorine from being degraded by UV rays from the sun, making it last longer in outdoor pools.
Frequency depends on pool volume, temperature, and usage. Regular testing with a chemical kit is the only way to determine exactly when to add more.
