Strong chemical or musty odor from spa water.

Safety first: Avoid using the spa until water is properly sanitized.

• Check sanitizer: Test and adjust chlorine/bromine levels to Everlast-recommended range.
• Shock spa: Perform a heavy shock treatment and run all Everlast pumps with air controls open for at least 30 minutes.
• Clean filters: Soak Everlast filter cartridges in a filter cleaner solution, then rinse thoroughly.
• Plumbing purge: Periodically use a spa plumbing purge product to remove biofilm from Everlast plumbing, then drain and refill.
