What Should I Do If My Swimming Pool is Green?

Discovering your swimming pool has turned green can be both alarming and disheartening. This common issue is typically due to algae growth, which thrives in environments where water chemistry is unbalanced. Addressing a green pool promptly is essential to restore its clarity and ensure it's safe for swimming.

Why is my Swimming Pool Green?

Algae proliferation is the primary reason for a pool turning green. Factors contributing to this include insufficient chlorine levels, imbalanced pH, poor filtration, and debris accumulation. Warm temperatures and sunlight further accelerate algae growth, making regular maintenance crucial.

How to Restore Your Pools Colour

  • Test and Balance the Water: Begin by testing your pool's water using a reliable testing kit. Focus on chlorine levels, pH, and alkalinity. Adjust these parameters to their optimal ranges to create an environment less conducive to algae.
  • Shock the Pool: Administer a high dose of chlorine, known as "shocking," to eliminate algae and other contaminants. Follow the product's instructions carefully, and consider performing this treatment in the evening to prevent sunlight from reducing its effectiveness.
  • Brush and Vacuum: Thoroughly brush the pool's walls and floor to dislodge algae, then vacuum to remove the debris. This physical cleaning complements chemical treatments, ensuring comprehensive algae removal.
  • Run the Filtration System: Operate your pool's filtration system continuously during the cleaning process to help clear suspended particles. Regularly clean or backwash the filter to maintain its efficiency.
  • Retest and Maintain: After the water clears, retest to confirm balanced chemistry. Implement a consistent maintenance routine, including regular testing, cleaning, and proper filtration, to prevent future algae outbreaks.

How to Prevent a Green Swimming Pool?

To keep your pool water sparkling and inviting, consider the following preventative strategies:

  • Regular Maintenance: Establish a routine that includes weekly testing and balancing of water chemistry, along with consistent cleaning.
  • Proper Filtration: Ensure your filtration system is appropriately sized for your pool and operates for an adequate duration daily to circulate and clean the water effectively.
  • Use of Algaecides: Incorporate algaecides as a preventive measure, especially during warmer months when algae growth is more prevalent.
