Wellis Crystal Foam Down (1 L)
What it does
Foam in spa water is caused by soap, lotion, body oils, or fabric softener residue. Crystal Foam Down breaks the surface tension that holds bubbles together, so they collapse. Importantly, it does NOT contain oils that would feed further foam formation.
When to use
Only when foam appears. This is a curative product, not a daily one. If you find yourself adding it frequently, the underlying cause is excess soap/lotion — investigate.
How to use
- With circulation running, add a small amount (5–10 ml typically) directly to the foam.
- Foam will drop within 1–2 minutes.
- Run circulation for 30 minutes.
- Plan a filter clean and partial water change if foam returns within a week.
Long-term solutions
- Shower before entering the spa.
- Rinse swimsuits in clean water (no detergent) before reuse.
- Use a cleaning disc to absorb surface oils between water changes.
