I wanted to let you know that the Standard Vortex Water Revitalizer 3/4'' is working GREAT! My hardness and pH are fine, but the water tastes as good as — if not better than — store-bought water. My hot tub is crystal clear. It is a little unusual, but when I drain water into a clean sink and look at it under bright light, I can see what appears to be very fine metallic particles in the water. It's actually quite interesting to observe.

Rod provided this picture showing the colour of his water before and after installing the Vortex Water Revitalizer. Rod explained that he has an old whole-house filter which produced brownish water, as shown in the bucket on the left. After installing a Whole House Vortex Water Revitalizer after the filter, the water became crystal clear, as shown in the bucket on the right.
