How to Fix Excess Foam
- Check water balance
If levels are off, adjust using FROG Balancing Basics® Kit. - Add a defoamer
- Add a swim spa shock like FROG Maintain® for Swim Spas
- If foam is persistent
If it’s been more than 6 months since the swim spa was drained, it’s time to drain and refill. Be sure to use a fresh Mineral Cartridge.
