ReFresh Granular Shock 68%
High-potency calcium hypochlorite shock engineered to kill bacteria, destroy algae, and oxidize the organic contaminants that cause dull water and that unmistakable "chlorine smell." Fast-dissolving, no CYA buildup, and strong enough to clear Northeast Pennsylvania problem water — whether you're opening in spring or recovering from a heavy regional storm.
Professional Strength
68% available chlorine — one of the strongest fast-dissolving shocks on the market. Maximum sanitizing power in every single bag.
Algae Killer
Ideal for treating active algae blooms or as a weekly super-chlorination treatment to stay ahead of green water all season.
No CYA Buildup
Cal-Hypo formula contains no cyanuric acid — won't raise your stabilizer levels over time or cause chlorine lock mid-season.
Fast-Acting
Dissolves rapidly for an immediate chlorine surge — gets your pool swim-ready faster than slower-dissolving shock alternatives.
Precision Testing
Digital analysis determines exactly how much shock your pool needs to hit breakpoint chlorination — no guessing.
