The ALPS Mineral Stones play a very important part of the 10 stage filtration process. The mineral stones are the 8th stage.

With nano silver particles to reduce bacteria, keep your water fresh, alkaline and mineralised.

The lifetime of the stones is 12 to 18 months.

Before use place the ALPS mineral stones in boiling water for 5 minutes, then place outdoors to dry naturally.

Spread them evenly to cover the surface area on the bottom of the lower tank (SPL-8). Repeat this process every 6 months for optimum mineral replacement.

The stones are compatible with Nikken PiMag & Nikken PiMag 10 Water Systems (not compatible with Nikken PiMag Waterfall)
