Find a Sustain DealerPool water turns cloudy often after heavy bather loads or a rain/wind storm because of the enormous amount of debris brought into the water. Water can also turn cloudy on its own. In either case, follow the steps below:
- Check your filter and circulation. Backwash or clean the cartridge filter to restore good flow, setting the pump for continuous operation for at least 24 hours, until the water is clear.
- Test the water for pH and chlorine levels. Free Available Chlorine (FAC) is usually low when the water is cloudy and pH is usually high. If this is the case, you need to shock treat your pool. Remember to adjust the pH to 7.2 - 7.4 before adding the Sustain Shock Treatment or Sustain Shield Energizer Tablets.
- If pH and FAC are within acceptable ranges, you have an unusual condition and you should take a one-quart sample to your dealer and have it tested for Total Alkalinity, Calcium Hardness and Cyanuric Acid levels.
Preventative Follow-up:
Test your water weekly and pay particular attention to pH and FAC. Make additions and adjustments as needed.
Eliminating Cloudy Pool Water
| Cause | Immediate Corrective Action | Preventive Follow-up |
|---|---|---|
| Poor filtration |
Check filter for proper operation and clean if dirty. Use a filter aid for cartridge and sand filters. Filter continuously until clear. |
Keep filter clean and operating properly. |
| Water not balanced |
Have your Sustain System Dealer test pool water for FAC, Total Alkalinity, pH, and Calcium Hardness. Balance pool water. |
Maintain balanced water |
| Heavy pool use |
If FAC <1 ppm, shock with Sustain Shock Treatment. If cloudy water is severe, use a flocculant. Vacuum settled solids. |
Maintain 1-3 ppm FAC. |
