I will research the zeta idea and I like the idea of alkalizing it. But is Bi-carb residual (with such frequent consumption will I turn into any kind of rock?) and is the 'real salt' a wise addition given its sodium quantity, especially if I drink a liter a day of the water? A Vortex machine might be beyond my budget. How long do the grains of rice need to soak before releasing appreciable alkaline factors?
