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. They may also be used as a shock treatment for
smaller 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.
Spas and Hot Tubs:
To increase the free chlorine level by 2.5ppm, add 5 grams (a teaspoon). On average you should need approx. 1 teaspoon per person using the spa.
Maintain a chlorine level of between 2-4ppm and a pH level of 7.2-7.6 in your spa.
Re-adjust the pH balance to between 7.2-7.6 for optimum bathing comfort.
