Wellis Crystal Metal Clear (1 L)
What it does
Binds dissolved metals into a soluble complex that won't precipitate onto surfaces or react with the chlorine sanitiser. Stops staining and prevents the green tint that copper from heaters can cause.
When to use
- Immediately after fresh fill if your tap water has visible iron content (yellow/orange tint).
- If using well or borehole water.
- If you notice green or brown staining starting to appear on the acrylic.
How to use
- Apply BEFORE chlorine sanitiser on a fresh fill.
- Turn circulation ON.
- Add the dose per the bottle (per 1 m³ of water).
- Run circulation for 4 hours.
- Then proceed with alkalinity / pH / sanitiser balancing.
Tip: at next refill, use the Pure Stream Water Softener prefilter to prevent metals from entering the spa in the first place.
