You'd think this was my first post or something. It initially showed CH as 0ppm (low pH maybe?) however the subsequent test showed 100 ppm and the fill water shows 70 ppm.

Speaking of "soft" water, any reason not to top off my vinyl liner IG with soft water other then the expense of the softener having to regenerate more frequently?
