If your pool is still green after 2 shocks, it may be due to insufficient chlorine levels, high pH, or the presence of phosphates. Check and adjust your pH levels to 7.2-7.6 and ensure your chlorine level is between 1-3 ppm. Also, consider using a phosphate remover as phosphates can fuel algae growth.

FAQs & Answers

  1. Why does my pool stay green even after shocking it? Your pool may stay green due to low chlorine levels, unbalanced pH, or the presence of phosphates that encourage algae growth, even after multiple shocks.
  2. How do I adjust pH levels to clear a green pool? Test your pool water and adjust the pH to between 7.2 and 7.6 for optimal chlorine efficiency and algae control.
  3. What role do phosphates play in pool algae? Phosphates act as a nutrient that promotes algae growth, so using a phosphate remover can help prevent persistent green water.
