The pool water is cloudy/milky and the bottom of the pool is no longer visible. What is the cause and how do I fix this?

Some possible causes include:

  • Too high a pH level
  • Filter times too short
  • No flocculation applied
  • Accumulation of impurities due to poor disinfection
  • Too many small suspended particles or pollution in the water

Some steps you can take to resolve this:

  • Clean your filtration system by performing a thorough backwash
  • Switch to continuous filtering
  • Use a pH cure to correct the pH of your pool to 7.0 – 7.4
  • Add a product to your pool water that helps prevent calcium deposits
  • Perform shock treatment with powdered chlorine to disinfect everything quickly
  • Use a double dose of flocculant and perform a thorough backwash afterwards
  • Add some algaecide products to your pool
