If you neutralise them, then:

1) a current must flow, where does that come from?

Dunno, but it's called an electrolytic device ...

2) the now neutral calcium atoms would immediately react with the
water to produce calcium hydroxide and hydrogen. So you're back where
you started: with calcium ions in solution.

Indeed - it's beyond my O-level chemistry to explain, but people seem
to think it works and they're probably not all snake-oil enthusiasts.

Is this thread still chugging on? The fact is that in my view, very hard
water should be somehow stopped, however they do it as it damages stuff
connected to it over time.
