Crystal-clear water starts with premium shock. Power Shock delivers powerful, fast-acting pool sanitization to keep your water clean, clear, and safe.
High-Powered Sanitization
While many of our competitors are selling smaller 'shrinkflation' packets of shock at lower concentration, Power Shock is still full-strength 68% Cal Hypo in a 1lb bag!
Crystal Clear Water, Instantly
Whether you're opening your pool, cleaning up after a storm, or dealing with murky water, Power Shock works quickly to restore sparkle and clarity.
Safe & Stabilizer-Free
Power Shock is stabilizer-free, meaning it won't increase cyanuric acid levels—perfect for regular maintenance without risking over-stabilization.
