A green pool is almost always caused by algae. Here's a step-by-step guide to clearing it up:

1. Test Your Water Chemistry: The first step is to test your water's pH, alkalinity, and chlorine levels. You can use a liquid test kit or test strips. Record the results. Ideally, your pH should be between 7.2 and 7.8, alkalinity between 80 and 120 ppm, and chlorine levels should be near zero if you have a significant algae bloom.

2. Balance the Water: Adjust your pH and alkalinity before shocking. Use pH increaser or decreaser and alkalinity increaser as needed, following the product instructions. Balancing the water first makes the shock more effective.

3. Shock the Pool (Superchlorinate): This is the most crucial step. You'll need to "shock" the pool with a large dose of chlorine. The amount of shock you need depends on the severity of the algae bloom. For a heavily green pool, you might need to triple or even quadruple the normal shock dose. Add the shock at dusk or night to minimize chlorine loss from the sun.

4. Run the Filter Continuously: Run your pool filter 24/7 until the water clears. Regularly clean or backwash the filter as needed. The filter is critical for removing the dead algae.

5. Brush the Pool: Brush the walls and floor of the pool thoroughly to loosen any algae clinging to the surfaces. This helps the chlorine reach and kill the algae.

6. Test and Adjust Again: After 24 hours, test your water again. Your chlorine level should be very high. If the water is still green, you may need to shock the pool again.

7. Add Algaecide (Optional): After shocking and the chlorine level drops to a safe level (around 3-5 ppm), you can add an algaecide to help prevent future algae growth. Follow the product instructions carefully.

8. Clarify the Water (Optional): Once the algae is dead and the water is still cloudy, use a pool%20clarifier to help the filter remove the remaining particles.

9. Vacuum the Pool: After the water clears, vacuum the pool to remove any remaining debris. If you have a multiport valve on your filter, vacuum to waste to avoid clogging the filter.

Important Considerations:

• Filter Type: Diatomaceous Earth (DE) filters are generally the most effective at removing algae. Sand filters may require a filter aid to remove finer particles.
• Phosphate Levels: High phosphate levels can contribute to algae growth. If you have recurring algae problems, test for phosphates and use a phosphate%20remover if necessary.
• Prevention: Regular testing and balancing of your water chemistry is the best way to prevent algae blooms. Maintain adequate chlorine levels, brush the pool regularly, and run your filter regularly.
