Revitalize Your Pool with Powerful 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 shocks designed to oxidize organic waste, kill bacteria, and restore your water to sparkling clarity. Whether you need a quick boost after heavy use, a weekly routine treatment, 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, and prevent algae growth with Algaecides.

Why Shock Your Pool?

  • Eliminate Contaminants – Breaks down sweat, oils, and organic matter chlorine struggles with.

  • Destroy Chloramines – Gets rid of combined chlorine that causes strong odors and eye irritation.

  • Clear Cloudy Water – Restores water brilliance and sparkle.

  • Boost Sanitizer Power – Resets chlorine effectiveness.

  • Prevent Algae Growth – Stops outbreaks before they spread.

Types of Pool Shock Treatments

1. Cal-Hypo Shock (Calcium Hypochlorite)

  • Powerful chlorine-based oxidizer.

  • Ideal for weekly use and heavy cleanup.

  • Adds calcium while treating water.

2. Dichlor Shock (Sodium Dichloro-S-Triazinetrione)

  • Stabilized chlorine shock with built-in UV protection.

  • Dissolves quickly with minimal effect on pH.

  • Great for outdoor pools exposed to sunlight.

3. Multi-Purpose Shock

  • Combines sanitizing, clarifying, and algae control.

  • Convenient all-in-one solution for busy pool owners.

4. Chlorine-Free Shock (Potassium Monopersulfate)

  • Non-chlorine oxidizer safe for swimming shortly after use.

  • Perfect for spas, indoor pools, and those with chlorine sensitivities.

  • Eliminates odors and restores sparkle without affecting chlorine levels.

When to Shock Your Pool

  • Weekly Maintenance – A regular shock keeps water safe and crystal clear.

  • After Heavy Pool Use – Parties, gatherings, and frequent swimmers introduce more contaminants.

  • After Rain or Storms – Runoff and debris can unbalance your water.

  • When Water Looks Cloudy – Shock treatments restore clarity and eliminate hidden waste.

  • Following Algae Treatment – Helps eliminate dead algae particles.

  • Seasonal Pool Opening & Closing – Start and finish each season with a clean, safe pool.

How to Use Pool Shock Safely

  1. Test Water First – Know your chlorine and pH levels before shocking.

  2. Pre-Dissolve (If Required) – Some shocks should be dissolved in water before adding.

  3. Add at Dusk or Night – Sunlight reduces chlorine effectiveness, so shock in the evening.

  4. Run the Pump Overnight – Circulation helps distribute the shock evenly.

  5. Wait Before Swimming – Follow label directions for safe re-entry times.

✅ FAQ – Pool Shock Treatments

Q: How often should I shock my 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.
