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

Health warning: Poorly sanitized water can cause skin and respiratory irritation. Avoid use until water is corrected.

• Test and balance water: Use a reliable test kit to check pH, alkalinity, and sanitizer levels. Adjust to Hanscraft-recommended ranges.
• Shock the spa: Add a non-chlorine or chlorine shock treatment according to label directions to oxidize contaminants.
• Clean or replace filter: Rinse the filter thoroughly; replace if heavily soiled or older than recommended.
• Flush plumbing (if recurring): Use a spa pipe flush product to remove biofilm from Hanscraft plumbing, then drain, clean shell, and refill with fresh water.

Maintain regular testing and filtration cycles to prevent recurring water quality issues.
