Why Would a Swimming Pool Look Cloudy or Milky if No One Has Had an Accident in It? Will It Still Be Safe to Swim In?

A cloudy or milky swimming pool can be caused by several factors, even in the absence of accidents. Here are some possible reasons:

  • High pH Levels: When the pH of the pool water is too high (above 7.8), it can cause calcium to precipitate out of the water, resulting in a cloudy appearance.
  • Low Chlorine Levels: Insufficient chlorine levels allow bacteria and other microorganisms to multiply, making the water cloudy.
  • Organic Matter: Debris like leaves, insects, and suntan lotion can decompose and release organic matter into the water, contributing to cloudiness.
  • High Algae Count: Algae growth can turn the water green or milky.
  • Metal Ions: Iron or copper in the water can react with chlorine to form metal oxides, which appear as cloudiness or discoloration.
