Low Residue & Fast Dissolving

Fast acting and dissolving, Power Powder Granular 70 works quickly to kill bacteria and control algae without leaving any noticeable residue behind. Even though it is a calcium based granular chlorinated shock, it won't significantly increase calcium hardness levels in the pool water. Power Powder Granular 70 works fast to eliminate contaminants currently in the water while preventing future potential algae growth.

Please Note: Depending on water chemistry levels such as high pH and Calcium Hardness, Cal-Hypo shock can cause possible turbidity or clouding of the water when added. This will normally clear up on its own.

Non-Stabilized Chlorine Pool Shock

There is no stabilizer or conditioner in Power Powder Granular 70 Cal-Hypo Pool Shock so adding it will not raise cyanuric acid (CyA) levels in the pool water if they are already elevated. With this in mind, it's best to add during evening hours while the filter pump is running to reduce UV degradation from the sun.
