Stabilised Chlorine Granules (Sodium dichloroisocyanurate dihydrate)
Chlorine granules with built in stabiliser, a premium sanitiser for swimming pool and spa water.
As a general guide for private pools and spas use a daily dose rate of 18 grams to 10m3 of pool water.
Heavy use and high temperatures may require an increased dosage.

Maintain a chlorine level of between 1 and 3 ppm or mg/litre. Use a suitable test kit to establish actual requirements and adjust as necessary.
