| The yellowishness you observed in high level hardness water is likely the metabolic wastes building in the skin & tissue. The high level of dissolved matter in the water prevents these wastes from leaving the body osmotically. In soft water, the wastes can be exuded through the skin as well as be filtered out by the kidneys etc. This leaves whites cleaner & reds brighter. ....I've read that there is a greater need for calcium in the diet in soft water, but not sure that standard quality pellets are not fully adequate in that regard. |
