Water is cloudy, foamy, or has a strong odor despite the spa running normally.

Safety: Do not use the spa until water chemistry is corrected.

• Step 1 – Test water: Use test strips or a liquid kit to check sanitizer, pH, and alkalinity. Adjust to AquaRest-recommended ranges.
• Step 2 – Clean or replace filter: Remove the filter cartridge and clean thoroughly. Replace if more than 1 year old or if pleats are damaged.
• Step 3 – Shock the spa: Add a non-chlorine or chlorine shock according to label directions to oxidize contaminants.
• Step 4 – Flush plumbing (if recurring): Use a spa plumbing flush product before the next drain/refill to remove biofilm from AquaRest plumbing lines.
