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

Safety first: Avoid using the spa until water chemistry is corrected.

• Test and balance: Use a test kit to check sanitizer, pH, alkalinity, and calcium hardness. Adjust to Arctic Spas recommended ranges.
• Shock the water: Add a non-chlorine or chlorine shock treatment per label directions to oxidize contaminants.
• Clean or replace filter: Rinse the filter thoroughly; replace if over 1 year old or heavily stained.
• Check ozone/salt system: Verify that the Arctic Spas ozone generator or salt system is operating (indicator lights, bubbles at injector). Repair or replace as needed.
• Drain and refill: If water is very old or TDS is high, drain the spa completely, clean the shell, and refill with fresh water.
