How to Get Rid of Hot Tub Foam with FROG Serene®

Foam collects along the edge of a hot tub.
  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. Add a Defoamer
  3. Add a hot tub shock like FROG Maintain®
  4. If Foam is Persistent
    If it’s been more than 6 months since the hot tub was drained, it’s time to drain and refill.
