Spa water is cloudy, foamy, or has a strong chemical or musty odor.

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

• Test water: Use Aquavia-recommended test strips or a test kit to check pH, alkalinity, and sanitizer (chlorine/bromine) levels. Adjust to recommended ranges.
• Shock treatment: Add a non-chlorine or chlorine shock product according to label directions to oxidize contaminants.
• Clean or replace filter: Rinse the filter thoroughly; deep-clean with a filter cleaner solution if heavily soiled. Replace if older than 1–2 years.
• Flush plumbing (if recurring): Use a spa pipe cleaner product before draining to remove biofilm from Aquavia plumbing lines, then drain, wipe the shell, and refill with fresh water.
