A pool shocked but still cloudy green indicates algae presence despite the shock treatment. It’s likely the shock treatment was insufficient or the pool has high levels of phosphates, which algae feed on. First, retest your water to ensure proper chemical balance; imbalances make it difficult for chlorine to work effectively. Vacuum the pool to remove debris and algae. Consider using a phosphate remover if levels are high. Brushing the pool walls and floor can also loosen algae, making it easier for the filter to remove it. Repeat the shock treatment if necessary, ensuring you use the right amount of shock for your pool's volume.
FAQs & Answers
- What causes a pool to stay cloudy green after shocking? A cloudy green pool after shocking usually indicates algae is still present, possibly due to insufficient shock dose, imbalanced water chemistry, or high phosphate levels feeding the algae.
- How can I remove algae if my pool remains green after shock treatment? Vacuum the pool, brush the pool surfaces to loosen algae, use a phosphate remover if needed, maintain correct chemical balance, and repeat the shock treatment with the appropriate dosage.
- Why is water chemistry important after shocking a pool? Proper water chemistry ensures chlorine and other chemicals work effectively to kill algae and bacteria, preventing cloudy or green water despite shock treatments.
