Dichlor Shock in Pool Care

Understanding Dichlor Shock

Dichlor shock, a form of chlorine, is a popular choice for sanitizing swimming pools. It contains a stable form of chlorine, known as sodium dichloro-s-triazinetrione, which is effective in killing bacteria, algae, and other harmful organisms in pool water.

Benefits of Using Dichlor Shock

  • Fast Dissolving: Dichlor shock dissolves quickly in water, ensuring rapid distribution of chlorine throughout the pool.
  • Stabilized Chlorine: It contains cyanuric acid, which protects chlorine from UV degradation, maintaining its effectiveness for longer periods.
  • Effective Sanitizer: It effectively kills and prevents algae and bacteria growth, ensuring a clean and safe swimming environment.

How to Use Dichlor Shock

  1. Test Water Balance: Before adding dichlor shock, test your pool water to ensure the pH levels are between 7.2 and 7.6.
  2. Calculate Required Amount: Determine the amount of dichlor shock needed based on your pool's volume. Generally, use 1 pound per 10,000 gallons of pool water.
  3. Distribute Evenly: Sprinkle the dichlor shock evenly over the pool surface, preferably in the evening to avoid sunlight reducing its effectiveness.

Maintenance and Safety

  • Regular Testing: Regularly test pool water to maintain appropriate chlorine and pH levels.
  • Safe Handling: Always handle dichlor shock with care, using gloves and goggles to avoid skin and eye irritation.
  • Storage: Store in a cool, dry place away from other chemicals and direct sunlight.

Cost and Efficiency

Dichlor shock is cost-effective, with the average price per pound varying depending on brand and quantity. It offers high efficiency in sanitizing pools with minimal impact on water chemistry.


Using dichlor shock in pool care ensures a clean, safe, and enjoyable swimming environment. Its fast action, stabilization, and cost-efficiency make it a preferred choice for many pool owners.
