I have added Iron out and res cleaner several times with no result and I mean several times
and it would not clear up/ staining everything I even went as far as to shock our well and it helped
for a bit but then it got bad again.
This was as far as im concerned the best decision for my family.
His test may have been off a bit as well but I tell you nice water is nice,
less shampooing and no tinny taste in your mouth.
I will have to check what brand it is when I get home and will let you know
