How to identify the cause quickly and restore clear, stable water.
Serving Santa Rosa & surrounding communities
Most Common Causes
- Imbalanced pH or alkalinity. Out-of-range balance can quickly make water appear dull or cloudy.
- Low sanitizer level. Weak sanitizer coverage allows contaminants to build up faster.
- Organic load from oils, lotions, or heavy use. High bather waste can create foam and persistent odor.
- Dirty or restricted filters. Poor filtration leaves suspended particles in circulation.
- Older water with high dissolved solids. Aged water is harder to stabilize with normal balancing steps.

Recovery Checklist
- Test and correct alkalinity, pH, and sanitizer. Correct chemistry order gives you a stable starting point for recovery.
- Shock water and circulate with cover open. Open-cover circulation helps gases dissipate during oxidation.
- Rinse or deep-clean filter cartridges. Clean media improves removal of fine particles causing cloudiness.
- Re-test after circulation and adjust in small steps. Small dosing changes reduce the risk of overcorrection.
