How to Deal with a Green Pool in Australia

Owning a swimming pool in Australia is a fantastic way to beat the heat and enjoy the outdoors. However, one common issue that pool owners face is the dreaded green pool. A green pool is not only unsightly but can also be a breeding ground for harmful bacteria and algae. In this blog post, we'll guide you through the steps to restore your pool to its sparkling blue glory.

Why Does a Pool Turn Green?

A pool turns green due to the presence of algae, which can overgrow, especially in hot weather. Algae thrive in pools with imbalanced water chemistry, particularly low chlorine levels. Other factors such as high pH levels, high cyanuric acid, and high phosphates can also contribute to algae growth.

Steps to Fix a Green Pool

1. Test the Water:Start by testing your pool water to determine the levels of chlorine, pH, cyanuric acid, and phosphates. You can use a pool testing kit or take a water sample to your local pool store for analysis.

2. Adjust pH Levels: The ideal pH level for pool water is between 7.2 and 7.6. Use a pH decreaser to lower the pH if it is too high. Follow the instructions on the product packaging for the correct dosage.

3. Shock the Pool: Shocking the pool involves adding a high dose of chlorine to kill the algae. Use a super shock chlorine product and follow the instructions for the correct amount to use based on your pool size. It's best to do this in the evening to prevent the sun from degrading the chlorine.

4. Add Algaecide: After shocking the pool, add a high-strength algaecide to kill any remaining algae. Follow the product instructions for the correct dosage.

5. Brush and Vacuum: Brush the walls and floor of the pool to dislodge the algae. Use a pool vacuum to remove the dead algae and debris from the bottom of the pool.

6. Run the Filter: Keep your pool filter running continuously for at least 24 hours to help clear up the water. Backwash the filter regularly to remove any trapped debris.

7. Use a Flocculent: If the water is still cloudy, use a flocculent to clump together the fine particles, making them easier to vacuum. Follow the product instructions for the correct dosage.

8. Maintain Proper Water Chemistry: Once your pool is clear, maintain proper water chemistry to prevent future algae growth. Keep chlorine levels between 2.0 and 4.0 ppm, pH levels between 7.2 and 7.6, and regularly test for cyanuric acid and phosphates.

Preventing a Green Pool

- Regular Maintenance: Skim the surface of the pool daily to remove leaves and debris. Brush the walls and floor weekly to prevent algae buildup.
- Consistent Chlorine Levels: Maintain consistent chlorine levels to keep the water sanitized and free of algae.
- Proper Filtration: Run your pool filter for at least 8-12 hours a day to ensure proper circulation and filtration.
- Regular Testing: Test your pool water regularly and adjust the chemical levels as needed to maintain a balanced water chemistry.

Conclusion

Dealing with a green pool can be a hassle, but with the right steps and regular maintenance, you can keep your pool water clear and inviting. By understanding the causes of algae growth and taking proactive measures, you can enjoy a sparkling blue pool all year round in sunny Australia.
