Strong chemical or chlorine smell from the spa water

Safety first: Avoid prolonged soaking in water with strong chemical odors; it can irritate skin and lungs.

• Test water: Check free chlorine, combined chlorine (if test available), and pH.
• Shock the spa: Add a shock treatment to break down chloramines, following product instructions.
• Ventilate: Run the pump with the cover open for a short period to allow gases to dissipate.
• Adjust pH: Bring pH into the recommended range (typically 7.2–7.8).

If odor persists, consider partially draining and refilling the spa and reviewing your regular maintenance routine.
