Our calcium hypochlorite granules with a high percentage
of available chlorine are fast dissolving and start to work in
This is to raise the chlorine level and shock your pool, spa
or hot tub water to destroy organic contaminants such a algae
To increase the chlorine level by 1mg/l add 150g granules per 100m³ of water.
Dissolve the shock granules in a clean plastic bucket. Add solution to the pool water near the return inlets.
