Water is cloudy or foamy even after filtration and chemical adjustment.

Safety: Use chemicals according to QCA Spas recommendations.

• Balance water: Test and adjust pH, alkalinity, and sanitizer to recommended ranges.
• Shock treatment: Add a shock dose to break down organics causing foam and cloudiness.
• Use foam reducer (temporary): Add a small amount of spa defoamer to reduce foam while addressing the root cause.
• Clean or replace filter: Dirty filters contribute to cloudy water; clean or replace the QCA Spas filter cartridge.
• Consider drain and refill: If TDS (total dissolved solids) is high or water is old, drain and refill the spa.
