Pool Shock Treatment

Swimming Pool Shock Treatment, also known as pool shocking, involves adding a large dose of chlorine or other oxidizers to the pool water to destroy contaminants, eliminate chloramines, and restore water clarity.

Why is Shock Treatment Necessary?

  • Eliminates Chloramines: Removes combined chlorine that causes strong odors and irritation.
  • Algae Removal: Destroys algae blooms and prevents their recurrence.
  • Water Clarification: Oxidizes organic matter, leaving the water clear and clean.

Types of Pool Shock

  • Calcium Hypochlorite: A granular chlorine product, best used at night to avoid UV degradation.
  • Sodium Hypochlorite: A liquid chlorine option for quick and effective shocking.
  • Non-Chlorine Shock: An oxidizing agent used for pools with high chlorine levels or sensitive swimmers.

How to Shock Your Pool

  1. Test the water to ensure pH is between 7.2 and 7.6 for optimal shock effectiveness.
  2. Dissolve granular shock in a bucket of warm water, if required.
  3. Distribute the shock evenly across the pool's surface.
  4. Run the pool pump for at least 8 hours to circulate the shock thoroughly.
  5. Retest chlorine levels before allowing swimmers to re-enter the pool.

When to Shock Your Pool

  • After heavy usage or pool parties.
  • Following heavy rainfall or storms.
  • When chlorine levels are low or combined chlorine is detected.
  • As part of routine maintenance, typically once a week.
