Does a water softener lower alkalinity? I know it exchanges the magnesium & calcium ions for sodium, but I wondered if it affact alk also. The previous owners of my pool (and house) apparently filled the pool with softened water but didn't balance it. I wondered if they used the softened water b/c of the high alk; the pool's TA was zero when I came on the scene. Upon filling my hot tub I discovered that my untreated source water was rather high in alkalinity (TA=290).
I posted about this yesterday but yesterday's posts seem to have disappeared.
