Curious about salt in water softener

turtleshopeJuly 14, 2012

We just had a water softener installed. I just noticed the local grocery carries "regular" salt and salt that is supposed to help deal with "rust." Iron in the water is a common problem around here.

Anyway I wondered what the chemical difference is between the two kinds of salt. None of the websites I visited would say, only that it was an "FDA Approved additive" for the iron.

Can anyone enlighten me?

And how useful is the additive?

Usually citric acid or the like is added to treat the iron but it doesn't work as well as a routine regimen using Iron Out or a similar product.

If you have a minimal amount of iron in your water then the best way to do it is...

For resin cleaning, once a month use 1/4 cup of Iron Out, Super Iron Out, Rust Pro etc. dissolved into a gallon or two of warm water and pour it into the 4" round tube
in the brine tank where the float is and then flush that with a quart of clear water. Wait two hours and then do a manual regeneration.
