I honestly had no idea where to put this so I figured this would be the best place..any who I'm about to fork out 500 bucks for a system called the nuvoh20. We have hard water (iron.. our tubs turn brown pretty quickly) I was wondering if anyone has one of these systems and if it actually works? I looked on amazon at their reviews but then realized this could possibly be from ghost reviewers getting paid to write positive reviews. Needless to say if im going to fork out that kind of cash for something I want to know if it works. Especially for the amount of iron in our water and the price.
