Cloudy pool water: the causes & solutions

Cloudy or milky pool water can have several causes. It is important to identify the cause before applying an appropriate solution:

  1. Balancing water chemistry: One of the most common causes of cloudy pool water is improper water chemistry. Test the pH and chlorine levels of your pool water and adjust them according to recommended levels. Properly balanced water chemistry prevents particles from binding, creating a type of slime that causes turbidity.
  2. Remove coarse debris: Before taking further steps, remove all visible debris from the water surface using a scoop net. This will prevent dirt from stressing the filter and making the situation worse.
  3. Filter maintenance: A clogged or inefficient filter can lead to turbidity. Check the filter and clean or replace it if necessary. Regular filter maintenance helps remove contaminants from the water effectively.
  4. Algae control: Excessive algae can make the water cloudy. Use an algaecide according to the recommended dosage to reduce algae and prevent it from developing further.
  5. Chlorine shock: If chlorine levels are too low, the water may become cloudy. Perform a chlorine shock to quickly increase chlorine levels and remove contaminants. Follow the manufacturer’s instructions carefully.
  6. Remove fine dirt: If there is fine dirt or sediment on the bottom, use a pool hoover to suck it up. Vacuum the entire bottom carefully and pay attention to any accumulations of dirt.
  7. Improve water circulation: Good water circulation is essential to evenly distribute and filter contaminants from the water. Make sure the pump and filter work correctly and optimize water flow.
  8. Use flocculant: Flocculant is a chemical that binds small particles in the water and makes them clump together into larger clusters, making them easier to remove via vacuuming or filtration.
  9. Prevent organic contamination: Make sure organic material, such as leaves and grass, does not end up in the pool. A good cover and regular removal of organic debris help prevent turbidity.
