| | Re: AZOO water softener and activated charcoal question
I'm not a whiz at chemistry, but I know that water softeners work by having resin beads, usually, that are "charged" with a salt, usually sodium chloride. The beads trade the sodium ions for calcium and magnesium ions until they are "full", then you recharge them with a salt bath. They work on cations only, not anions, so the chloride ions are not involved. (I'm not at all clear on this part.) Now, you know as much about softeners as I do!
You can buy potassium chloride for water softeners, or I have been told you can, but it is more expensive than sodium chloride. And, I think salt substitute sold in grocery stores are potassium chloride. The label will tell you that.
