The water (especially the hot water) in my house smells like rotten eggs. I have had the water tested and been told that I have the following:
Hardness 13 grains per gallon
Iron at 1.16 (PPM?)
Manganese at .9 (PPM?)

I have been told by one company that I need a sediment filter, then an iron filter, and then a water softener.

Another company told me that I do not need the iron filter and that the water softener will solve the issue.

I have read different threads here and elsewhere that say that the water softener can handle the iron, but that it will cause issues over time with the water filter. I am looking for some advice.
