Rated 5.0 out of 5.0 by Whites stay white When I purchased my house the previous owners left some off brand salt here. It wasn't long before I began to notice my white laundry turning a brownish yellow color. I began to wonder if it was iron in my water and switched to Diamond Crystal Iron Fighter pellets. It was amazing, my whites are white! January 17, 2015
Rated 5.0 out of 5.0 by This quality salt. I have uesd other softener salts and keep coming back to Diamond brand salt. For what ever reason the salt tab give more gallons of purified water than the other brands. I compare it to gas mileage. I get better water mileage with diamond than the other brands. Which also mean I don't have do the job of filling the softener as often. April 18, 2014
Rated 5.0 out of 5.0 by The right product for the right job I am totally pleased with my purchase of Red Out Water Softner pellets. It completely took the rust out and made the water so very soft, that when you took a shower you came out feeling so refreshed and my hair so soft that I di not need any conditioner. October 3, 2012
Rated 5.0 out of 5.0 by Good iron removal Scaling has ceased accumulating on my appliances and fixtures, but more importantly it is great at iron removal.  I had placed, and forgot, my Iron Fighter loaded softener was on bypass for maintenance leaving only the iron filter which removes most of my iron.  My water started turning brownish the next day, I remembered and turned the softener back on and instantly had crystal clear water again.

Rated 1.0 out of 5.0 by Worst product I ever bought Cargill has done their customers a very big dis service with this product. It does not hold a candle to the Red Out I used to buy.(50 bags at a time) Now I am looking for a product to replace this Iron Fighter because it does not fight Iron. I am constantly spraying my sinks and tub with an Iron destroyer because Iron Fighter does not do what they say it will. January 26, 2014
