Total Pool Chlorine

Total chlorine is the sum of free chlorine and combined chlorine present in pool water.

Understanding Total Chlorine

In pool water chemistry, total chlorine represents the combined amount of:

  • Free Chlorine (FC): The active and available chlorine that sanitizes pool water.
  • Combined Chlorine (CC): Chlorine that has combined with contaminants and is no longer effective as a sanitizer.

The relationship can be expressed as:

Total Chlorine (TC) = Free Chlorine (FC) + Combined Chlorine (CC)

Monitoring total chlorine helps pool operators assess water quality and determine the effectiveness of the sanitation process.

Importance of Monitoring Total Chlorine

  • Health and Safety: Ensures that the pool water is properly sanitized, reducing the risk of waterborne illnesses.
  • Water Quality: Helps identify the presence of combined chlorine, which can cause unpleasant odors and irritation.
  • Maintenance Efficiency: Assists in determining when to perform shock treatments to eliminate combined chlorine.

Testing and Maintaining Total Chlorine Levels

  • Use appropriate test kits to measure both free and total chlorine levels.
  • Calculate combined chlorine by subtracting free chlorine from total chlorine.
  • Maintain free chlorine levels within the recommended range (typically 1-3 ppm) to ensure effective sanitation.
  • If combined chlorine levels exceed 0.2 ppm, consider performing a shock treatment to oxidize and remove contaminants.
