Benefits & What Makes It Different
68% Calcium Hypochlorite Formula
Delivers fast-acting available chlorine to oxidize organic waste and eliminate combined chlorine without adding stabilizer.
Zero Cyanuric Acid Buildup
Unlike stabilized shocks, this cal hypo formula sanitizes effectively without pushing cyanuric acid past the ideal 30–50 ppm range.
Fast-Acting Deep End Broadcast
Granules disperse across the deep end to quickly elevate available chlorine levels by 5 to 10 ppm.
Product Details
Calcium Hypochlorite (68%)
Add 10–20 ounces (approx. 1 lb) per 10,000 gallons of water weekly for 5 to 10 ppm available chlorine.
Compatibility
- Compatible with all plaster, vinyl, and fiberglass pool surfaces when properly broadcast and brushed
- Never mix directly with other dry pool chemicals, trichlor pucks, or acids in a skimmer or bucket
When To Use This
Pro Tip
Always broadcast 1 lb per 10,000 gallons at dusk to prevent UV rays from degrading unbonded chlorine. In regions with naturally hard source water, keep an eye on calcium hardness to stay within 200–400 ppm.
Common Questions & Instructions
How much Poolife Rapid Shock should I add per 10,000 gallons?
Broadcast 10 to 20 ounces (about one 1 lb bag) per 10,000 gallons directly into the deep end with the filter pump running to provide 5 to 10 ppm of available chlorine.
Does Poolife Rapid Shock add cyanuric acid to pool water?
No. Because the active ingredient is 68% calcium hypochlorite, it will not increase cyanuric acid levels, making it ideal for pools already at target stabilizer levels.
When is it safe to swim after using Poolife Rapid Shock?
Add during evening hours and let circulate overnight. Check water chemistry before swimming to ensure free chlorine has returned to the safe 1–3 ppm range.
