Common Questions & Instructions
How do you install Sirona Spa Minerals in a high-flow hot tub?
For hot tubs equipped with skimmer filters and pump motors of 2.5 HP or greater, place the 58 grams cartridge in the filter well outside the filter cartridge to ensure proper water flow and mineral dispersion.
Do I still need chlorine or bromine with Sirona Spa Minerals?
Yes, mineral sanitizers work as a supplement. You must maintain a baseline chlorine or bromine level of at least 1ppm in water up to 600 gallons.
Does Sirona Spa Minerals affect pH or calcium hardness?
No, Silver Chloride does not alter pH, total alkalinity, or calcium hardness levels. In hard water areas, maintain calcium hardness at 200–400 ppm to avoid scale on the cartridge.
