  1. Check Water Balance
    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
  2. Shock
    Add a hot tub shock like FROG Maintain® to the water.
  3. Check Your Bromine Cartridge
    Remove the Bromine Cartridge from your system. Drain and shake to see if you hear any bromine inside. If empty, replace with a new one.
  4. Check Your Mineral Cartridge
    Even if you hear minerals inside, they may be used up. Replace the blue Mineral Cartridge every 4 months.
  5. Clean Your Filter
    Ensure proper water flow and remove any debris from the hot tub.
