Hi Greg, Water softening simply substitutes the "hard"stuff in tapwater (calcium carbonate, calcium chloride, etc) for sodium chloride, AKA salt (ionic material). It's not a direct 1 to 1 exchange either, so essentially, the soft water "quality" compared to tap water , from the D.I. exchange bed perspective, is lower. I guess the answer to your question (which, BTW, was truncated by the technet digest process for some reason) is NO.

For those who don't love us, may God turn their hearts. And if God can't turn their hearts, may He turn their ankles, so we'll know them by their limping.
