Top Causes of Cloudy Pool Water
1. Poor filtration. A dirty or undersized filter can’t remove fine particles. Clean or replace your filter media first.
2. Low chlorine. Insufficient sanitizer allows bacteria and algae to cloud the water.
3. High pH or alkalinity. Imbalanced chemistry causes calcium to precipitate, creating cloudiness.
4. Heavy debris. Rain, leaves, and dust overwhelm the filtration system.
5. Algae bloom. Early-stage algae makes water hazy before turning green.
How to Clear Cloudy Water
- Shock the pool with chlorine
- Run the filter 24/7
- Clean or backwash the filter
- Test and balance pH and alkalinity
- Use clarifier if particles are too fine for the filter
