It is not uncommon for pool water to suddenly turn cloudy — sometimes overnight. This problem may appear gradually after a pool party, or quickly after heavy rain. No matter how it happens, cloudy water is a clear sign that something is wrong with your pool and needs to be addressed.
Causes of Cloudy Pool Water
1. Poor Filtration
When the filtration system is not working properly, tiny particles remain suspended in the water instead of being removed. These particles are usually dust, dirt, algae, or other organic matter.
Check your filter pressure gauge: If the reading is too high, backwash the filter.
Replace filter media if needed: If backwashing does not solve the issue, the filter sand or cartridge may need replacement.
Regular maintenance:** Cleaning and maintaining the filter ensures your pool circulation system works efficiently.
2. Inadequate Disinfection
(a) Low chlorine levels
Free chlorine is consumed quickly by sunlight and swimmer activity. When chlorine drops below **1.0 ppm**, algae and bacteria can multiply, turning the water cloudy.
