Efficient Pool Disinfection with Calcium Hypochlorite

Calcium hypochlorite
Calcium hypochlorite is a commonly used chemical for pool disinfection, known for its effectiveness in killing bacteria and preventing the spread of waterborne illnesses.

Understanding Calcium Hypochlorite

Proper Storage

Store calcium hypochlorite in a cool, dry place away from direct sunlight. Exposure to sunlight and moisture can lead to the breakdown of the chemical, reducing its effectiveness.

Handling and Mixing

Dosage Calculations

Accurate dosage is crucial for effective pool disinfection. Calculate the required amount based on the pool size, water volume, and current chlorine levels. Use a reliable pool water testing kit to determine chlorine concentrations.


For granular forms of calcium hypochlorite, consider pre-dissolving it in a bucket of water before adding it to the pool. This helps prevent localized concentrations and minimizes the risk of skin or eye irritation for swimmers.

Application Timing

Add calcium hypochlorite to the pool during the evening or night to maximize its effectiveness. Sunlight can cause the rapid degradation of chlorine, reducing its disinfecting capabilities.

Regular Monitoring

Regularly monitor chlorine levels in the pool to ensure they remain within the recommended range. Periodic checks help prevent both over-chlorination, which can be harmful to swimmers, and under-chlorination, leading to inadequate disinfection.

pH Balance

Maintain the pH balance of the pool water within the recommended range (typically 7.2 to 7.8) to optimize the effectiveness of calcium hypochlorite. An appropriate pH level ensures that chlorine works efficiently in killing bacteria and germs.

Safety First

Prioritize safety by informing pool staff and users about the presence of chlorine in the water. Install warning signs, provide adequate ventilation in pool areas, and have emergency procedures in place in case of accidental exposure.

Proper Disposal

Dispose of any unused or expired calcium hypochlorite according to local regulations. Avoid flushing it down drains or disposing of it in a way that may harm the environment.
