If your pool water has turned green, it is most likely due to algae growth caused by an imbalance or lack of chlorine. Here is what you should do to fix a green pool:
Steps to Fix a Green Pool
- Test and balance your pool water : Check and adjust the pH to between 7.0 and 7.6 (ideally close to 7.0 for shock treatment). Also, test chlorine levels and other chemicals to ensure proper balance
- Clean the pool thoroughly : Remove leaves, debris, and algae from the pool surface and bottom using a net and vacuum. Brush the pool walls and floor to loosen algae deposits
- Run the filtration system continuously : Keep your pump and filter running for 24-48 hours to help clear the water. Backwash or clean the filter regularly during this time to maintain efficiency
- Shock the pool : Add a large dose of chlorine (shock treatment) to kill algae. Dissolve chlorine granules in warm water first, then distribute evenly with the pump running. This step is crucial to clear green water
- Use algaecide : After shocking, add an algaecide according to the product instructions to kill remaining algae and prevent regrowth
- Optional clarifiers or flocculants : For very dark or cloudy green water, you may need to add a clarifier or flocculant to help remove dead algae particles from the water
- Maintain ongoing pool care : After clearing the pool, continue to monitor and maintain proper chemical levels, clean filters, and remove debris regularly to prevent algae from returning
- Cover the pool : Using a pool cover can reduce algae growth by limiting sunlight and helping chlorine last longer in the water
This process typically takes a few days to restore clear water but following these steps will effectively clear your green pool
