Excessive foam on water surface during use

Safety first: Use chemicals as directed.

• Skim foam: Manually skim off foam with a net or bucket.
• Adjust water balance: Increase calcium hardness to recommended levels and balance pH/alkalinity.
• Shock water: Apply a shock treatment to break down organics.
• Drain if needed: If foaming persists, drain and refill the Sunrise Spas hot tub and clean the shell and filters.
