Spa water is foamy, with persistent bubbles even when jets are off.

Safety first: No electrical work is needed.

• Test water: Use a Clearwater Spas-approved test kit or strips to check sanitizer, pH, alkalinity, and calcium hardness.
• Shock spa: Add a non-chlorine shock or chlorine shock per label directions to oxidize contaminants.
• Use foam reducer: Add a spa defoamer product as a temporary fix.
• Drain and refill: If foam persists, drain the spa, wipe the shell, rinse filters, and refill with fresh water.
