Cloudy water that does not clear with normal filtration.

Safety first: Handle clarifiers and chemicals per manufacturer instructions.

• Clean or replace filter: Thoroughly clean the filter or install a new cartridge.
• Increase filtration: Extend filter cycle durations on the Coast Spas control panel.
• Balance water: Adjust pH, alkalinity, and sanitizer to recommended ranges.
• Use clarifier: Add a spa clarifier to help the filter capture fine particles.
• Drain and refill: If cloudiness persists, a full water change may be necessary.
