How to Fix Cloudy Water

Proper balance is required for things to work effectively. If levels are off, adjust using FROG Balancing Basics® Kit.- Total Alkalinity: 80–120 ppm
- pH: 7.2–7.6
- Total Hardness: 150-250 ppm
- Shock
Shock the water with FROG Maintain® for Swim Spas or a non-chlorine shock. - Check the SmartChlor® Cartridge
Remove the SmartChlor Cartridge from your system. Drain and shake to see if you hear any SmartChlor inside. If empty, replace with a new one. - Check the Mineral Cartridge
Even if you hear minerals inside, they may be used up. Replace the blue Mineral Cartridge every 4 months. - Clean the filter
Ensure proper water flow and remove any debris from the hot tub.
