Water appears cloudy or milky despite filtration

Safety first: Do not use the spa if water is very cloudy or smells strongly; it may harbor harmful bacteria.

• Test water: Use Bestway-compatible test strips to check sanitizer, pH, and alkalinity levels.
• Adjust chemicals: Bring sanitizer, pH, and alkalinity into the recommended ranges.
• Shock treatment: Apply a non-chlorine or chlorine shock product according to label directions to oxidize contaminants.
• Clean/replace filter: Rinse or replace the filter cartridge and run the pump continuously for several hours.

Persistent cloudiness may require partial or full water replacement and a thorough cleaning of the spa surfaces and filter housing.
