Wellis Crystal Spa Cleaner (Pipe Cleaner)
What it does
Inside spa plumbing, biofilm gradually builds up — a slimy bacterial coating that can't be reached by surface chlorine. Even after a water change, the biofilm in the pipes can quickly re-contaminate fresh water. Crystal Spa Cleaner penetrates and dissolves this layer.
When to use
Once per quarter, immediately before draining the spa for a full water change. Wellis recommends a quarterly water change for private use.
How to use
- Add the dose per the bottle to the spa with full water (still bathable level).
- Run all jets and the circulation pump for 15 minutes.
- Let it sit for 30 minutes.
- Run jets again for 5 minutes.
- Drain the spa via the 2" fast-drain valve.
- Wipe down the empty acrylic with a soft cloth.
- Refill through the Pure Fill prefilter.
Do NOT bathe in spa water that has Crystal Spa Cleaner in it. The product is for cleaning only.
