I been using the cal-mag supplement from an for years now but can't seem to find it where I am at and I need something now. Just wondering what other people are using for this.
I wanna replace r/o and cal-mag with tap at 240 ppm.... I read that the tds in tap water are from lime, which is calcium and magnesium....
can I bag the r/o and cal-mag for straight tap.....?
