In The Swim Super Pool Shock
Achieve crystal clear pool water with In The Swim Super Pool Shock. This powerful granular shock utilizes a high-strength 73% Calcium Hypochlorite active ingredient, delivering a minimum of 70% available chlorine to rapidly eliminate algae, bacteria, and contaminants. It dissolves quickly, leaving behind minimal residue, making it excellent for spring openings or routine weekly superchlorination. Importantly, this shock is non-stabilized, ensuring it will not increase your pool's Cyanuric Acid (CyA) levels. For effective treatment, apply one 1 lb. bag per 10,000 gallons in the evening while the pump is running.

What customers say
Customers overwhelmingly praise In The Swim Super Pool Shock for its powerful performance in achieving crystal clear water. Its primary strength is rapidly eliminating tough algae and clearing murky conditions, often showing results overnight. Pool owners value the high chlorine concentration, which provides the robust shock treatment needed for regular maintenance or storm recovery. A key positive factor is the excellent value, especially when buying in bulk, making it economical compared to retail alternatives. While highly effective, some users note minor handling challenges with the calcium hypochlorite formula, occasionally reporting temporary cloudiness or the need to pre-dissolve granules carefully to prevent settling. Overall, the consensus confirms its superior sanitizing power and reliability.
