5kg Stabilised Chlorine Granules, Swimming Pool Chemicals

Chemical: Sodium Dichloroisocyanurate
Function: A granular form of chlorine sanitiser for pools and spas. Also used as a shock treatment on small above ground pools.

Dosing Instructions (Pool):

To increase the free chlorine by 1 part per million add one scoop (100 grams) per 50 cubic metres (10,000 gallons).
For a shock dose add 750 grams per 10,000 gallons. Please note this might need to be doubled or even trebled if algae is present.
Dissolve granules in warm water in a plastic bucket or place in skimming basket or strainer.
If using a feeder or dispenser ensure that the granules used are the same chemical (Sodium Dichloroisocyanurate). If another material has been used wash the feeder out thoroughly before adding granules.
Maintain a chlorine level of 1 to 3 ppm and a pH level of 7.2-7.6 in your pool.

Dosing Instructions (Spa):

To increase the free chlorine by 2.5 parts per million add 5 grams (a teaspoon). Note: On average you should need approx. 1 teaspoon per person using the spa.
Maintain a chlorine level of 2 to 4 ppm and a pH level of 7.2-7.6 in your spa.
