Active Ingredient: 73% Calcium Hypochlorite

In The Swim’s Super Pool Shock has the highest percentage of Calcium Hypochlorite available for a super strength and concentrated pool shock. Some other pool shocks have a lower percentage of the active ingredient with a higher percentage of inert ingredients which reduce the amount of chlorine sanitizer that is ultimately added to your pool.

Don’t settle for anything less when looking for a pool shock to effectively treat pool problems like algae blooms and swimming accidents fast. As the chlorine dissolves in the water, it forms hypochlorous acid which is what kills and eradicates algae and bacteria.
