Sirona Spa Mineral Stick

The stick uses silver chloride to naturally purify your spa water. It works alongside your existing sanitizer—like chlorine or bromine—to neutralize bacteria, allowing you to use significantly less harsh chemicals while maintaining water clarity.

No, this is not a standalone sanitizer. It is designed to work in tandem with low levels of chlorine or bromine, helping you reduce your chemical usage by up to 50 percent while keeping the water safe and clean.

Installation is straightforward. You simply place the stick directly into the center of your existing spa filter cartridge. It is designed to fit most standard spa filtration systems.

For optimal performance, you should replace the mineral stick every four months. You should also replace it whenever you drain and refill your spa.

The mineral stick itself is designed to be neutral and should not significantly impact your water's pH or alkalinity. However, you should still test your water regularly to ensure your sanitizer levels and pH remain within the recommended range.
