How to use Chlorine Shock/Chlorine Granules.
A measurement of the water quality is highly recommended before adding ChlorineShock. When the alkaline and pH levels are right, chlorine shock can be added. If the water is green, it is strongly recommended to brush it loose first. For a good Chlorine Shock we suggest 15 g/1,000 liters, this gives a high concentration of chlorine to kill off algae. For a weekly dose this may be 10 g/1,000 liters.
Safety
Always seal the container tightly and keep out of the reach of children.
