Wellis Kristallklares Wasser
Die Wellis Crystal-Serie – ausgestattet mit dem gleichen WellisGuard™ Desinfektionssystem, das Sie auch in den Whirlpools finden. Desinfektionsmittel, pH-Regulierer, Oxi-Spüler, Flockungsmittel, Anti-Schaum, Filterspüler und Vorbehandlung des Füllwassers.
Wellis Crystal is the same water-care chemistry Wellis use to commission their factory test pools — engineered for Wellis spa materials and the WellisGuard™ sanitiser system, while also working with most modern third-party hot tubs and swim spas. The full range covers everything from sanitisers and balancers to flocculants, anti-foam, and pre-fill water treatment.
The five essentials
- Test strip — Crystal Pool Check 5-in-1 for free/total chlorine, pH, alkalinity, and hardness.
- Sanitiser — Crystal Chlorine Tablets in a floating dispenser, or active oxygen for chlorine-free use.
- pH control — Crystal pH Down when pH rises above 7.6.
- Alkalinity — Crystal Alkalinity Balancer stabilises pH so it doesn't swing.
- Filter cleaning — Crystal Filter Cleaner weekly rinse; monthly deep-soak.

Important — please read before use
Always follow the dosing instructions printed on the product label and on the Safety Data Sheet (SDS) supplied with the chemical. Consult your Wellis spa user manual for product-specific water-care guidance applicable to your model, water source, and usage pattern. Never mix water-care chemicals together directly — always add each product separately to circulating spa water with the pump running.
