I live in Central Illinois and have major issues with iron sulfide buildup and other hardeners in the well water. I have tried an iron filter and water softener, but the buildup continues. We had one that worked with and one that worked without potassium permanganate in the iron filter.

I have read about new products such as the NuvoH2O that uses a chelating agent. Are these any improvement over the salt based systems? Do you have any suggestions?
