💡 Helpful Tips & Best Practices

🫧 Leisure Time Foam Down

Foam happens naturally from body oils, lotions, shampoos, and detergents left on swimwear. Use de-foamer lightly — a little goes a long way.

To prevent foam:

  • Dedicate a swimsuit just for spa use.
  • Rinse it in hot water only (no detergent) before use.

🧼 Filter Care

Keeping your filters clean helps your spa run efficiently and reduces chemical use.

  • Rinse weekly with a garden hose or faucet.
  • Deep clean twice a year by soaking with a filter cleaner to remove oil buildup.

🪶 Cover Care

Your cover protects your investment — take care of it!

  • Use a non-alcohol, non-silicone, non-wax conditioner (we recommend 303 Protectant).
  • Apply at least four times per year, especially in dry climates.
  • Helps prevent cracking, fading, and water absorption.
