Strong chemical smell or skin/eye irritation when using the spa.

Safety first: Exit the spa immediately if you experience breathing difficulty, dizziness, or severe irritation.

• Test water:
  • Use test strips to measure sanitizer and pH levels.
• Adjust chemicals:
  • If sanitizer is high, remove the cover and allow levels to drop naturally.
  • Raise pH if it is below the recommended range.
• Improve ventilation:
  • Leave the cover partially open for a period to allow gases to dissipate.
• Partial water change:
  • If levels are severely out of range, drain 25–50% of the water and refill with fresh water, then rebalance.
