Instead of compensating this with reverse osmosis or distilled water, a kalkwasser water mix is preferred, whereby a low dose of calcium and buffer components are added in conjunction with water.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDirections:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAdd 2-3g Kalkwasser powder to 5L RO water.
