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

Safety: Do not use the spa if water is visibly contaminated or has a strong unpleasant odor.

• Test water: Use Canadian Spa Company test strips or a liquid kit to check sanitizer, pH, and alkalinity. Adjust to recommended ranges.
• Shock the spa: Add a non-chlorine or chlorine shock treatment according to spa volume.
• Clean filters: Remove and deep-clean filters with a filter cleaner solution. Replace if over 1–2 years old.
• Flush plumbing: Periodically use a spa pipe cleaner product to remove biofilm, then drain and refill the spa.

Persistent water issues may require reviewing your maintenance routine or consulting Canadian Spa Company water care guidelines.
