# Pool Shock | Chlorine, Cal-Hypo & Non-Chlorine Shock ## Revitalize Your Pool with Powerful Pool Shock Treatments Even with regular sanitization, your pool water is constantly exposed to contaminants — sweat, body oils, cosmetics, pollen, rainwater, and other organic material. Over time, these impurities overwhelm chlorine and leave your water looking dull, cloudy, or even green. That’s where **pool shock treatments** come in. At Benchmark Pool Supply, we carry a full range of **pool shock chemicals** designed to oxidize organic waste, kill bacteria, and restore your water to sparkling clarity. Whether you need a quick chlorine boost after heavy use, a weekly [routine treatment](/collections/pool-chemicals "Pool Chemicals"), or a chlorine-free option, our shock products help you maintain a safe and inviting swimming environment. Boost your sanitation routine with **Sanitizers**, improve clarity with [**Clarifiers**](/collections/clarifiers "Pool Clarifiers for clear water fast"), and prevent algae growth with **[Algaecides](/collections/algaecides "Swimming Pool Algaecides") or [Phosphate Removers](/collections/phosphate-remover "Pool Phosphate Removers")** * * * ## Why Shock Your Pool?

A: Weekly shocking is recommended during the swim season, plus after heavy use, storms, or cloudy water. * * * ### Q: Can I swim right after shocking? A: It depends on the product. Chlorine shocks typically require 8–24 hours, while chlorine-free shocks may allow swimming in as little as 15 minutes. * * * ### Q: Is chlorine-free shock effective? A: Yes, chlorine-free shocks are powerful oxidizers that remove waste and restore water clarity without raising chlorine levels. * * * ### Q: Will shocking my pool affect pH or alkalinity? A: Some shocks can temporarily raise or lower pH. Always retest your water after shocking. * * * ### Q: Do I need to shock a saltwater pool? A: Yes. Saltwater generators maintain chlorine, but shocks are still needed for heavy use, storms, or problem solving. * * * ### Q: Can I use pool shock in a spa or hot tub? A: Yes, but use chlorine-free or spa-specific shocks for smaller water volumes. * * * ### Q: What is the best pool shock for cloudy water?
