Spa water is cloudy, foamy, or has a strong odor despite normal filtration cycles.

Safety first: Do not use the spa if sanitizer levels are low or water is visibly contaminated.

• 1. Test water: Use test strips or a liquid kit to check sanitizer, pH, alkalinity, and hardness. Adjust to Sundance-recommended ranges.
• 2. Clean or replace filter: Rinse the filter thoroughly; if older than 1 year or heavily stained, replace it.
• 3. Increase filtration: Adjust the control panel to run longer or more frequent filtration cycles.
• 4. Shock the spa: Add a non-chlorine or chlorine shock according to label directions to oxidize contaminants.
• 5. Check ozone/UV: Verify that the ozone or CLEARRAY system is operating if your model is equipped.
• When to call a technician: Persistent water quality issues may indicate a hidden circulation or ozone/UV problem that needs professional evaluation.
