I just recently purchased a home and have found evidence of "hard water" such as water stains in the toilet bowl and shower tub. The biggest evidence of course being the feel of a hot shower compared to one using a water softener. There are many articles about installing a water softener system but my question is about the merit of "magnetizing" products such as system sold by Sophtec. Do these products work or is it simply too good to be true? Thanks!
