This is easy to do yourself. I used Nelson Cation Resin which is a standard high-capacity, high purity, 8% crosslink mesh. .75 cubit feet per tank (Kintico K60) And yes, this will treat water with iron in it. Remember however, that over time iron will foul resin and can reduce flow rate. I found the best price at water-softeners-filters.com. Please subscribe, like and comment.
