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.

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.
