Doheny’s Super Pool Shock is our best-selling pool shock. It kills algae, bacteria, and other organic contaminants to quickly turn your pool water from cloudy to clear. Quick dissolving and fast-acting, it contains 68% calcium hypochlorite as the active ingredient to sanitize and help clear even the most contaminated pools.
This versatile granular chlorine pool shock is highly effective for your pool opening in the spring. Its 65% available chlorine gives your swimming pool a quick chlorination boost to keep your pool water crystal clear and free of contaminants throughout the swim season.
Doheny’s Super Shock for pools are sold in easy-to-use one-pound bags in quantities of 6, 12, 24, and 48 with a shelf life of up to 18 months, providing a great value for your daily chlorination and pool chemical maintenance needs. The regular dosage of our Super Shock is one bag for every 10,000 gallons of water. However, spring openings or pools that sustain extensive sunlight or have excessive algae blooms may require double or triple doses to properly sanitize pool water.
Does Super Pool Shock kill algae or just clear cloudy water?
Super Pool Shock is formulated to kill algae, bacteria, and organic contaminants, not just improve water clarity. Shocking helps eliminate the source of cloudiness while restoring sanitizer effectiveness.
Can I shock my pool if chlorine levels are already high?
If chlorine levels are already elevated, shocking may not be necessary. Super Pool Shock is most effective when chlorine is low or struggling to stay active due to heavy use, algae, or organic buildup.
