Cloudy or dull pool water can be related to improper chemical balance, or fine debris suspended in the water. The first step to resolving a cloudy pool water problem is testing the pool water for Comined Chlorine, pH, Alkalinity and Calcium Hardness. The two areas that are most likely to cause cloudy pool water are the pH and the Calcium Hardness. If the pool chemical levels are not within the suggested ranges below, adjust and run the pool filter system for 12-24 hours before re-testing. If the pool was clear before and just became cloudy immediately after adding products to adjust the pool chemical levels (such as pH increaser or decreaser), the pool water may still be adjusting to the changes youve made. Filter for 12-24 hours before re-testing, and the water should clear. - Free Chlorine: 1-3 ppm
- pH: 7.2 7.6
- Alkalinity: 80 120 ppm
- Calcium Hardness: 200 350 ppm
If all the pool chemical levels test in range, the cloudy pool water is caused by fine debris suspended in the pool water. You should backwash or clean your pool filter following the manufacturers instructions, and run the pool filter system continuously for 24 to 48 hours. If the water conditions have not significantly improved you should add a clarifier pool chemical to the pool water to help your pool filter remove the fine debris from the water. Continue filtering for 12 to 24 hours. If the water conditions have not significantly improved you should add a second dose of clarifier, or a stronger clarifier chemical. It is important that you continuously filter the pool water until the water is clear, and closely monitor your pool filter pressure. Backwash or clean the pool filter as needed, following the pool filter manufacturers instructions. |
