I have posted several times about a pool with serious iron staining, and how I have been trying to remove the stains with products like the CuLater. It just so happens that the tenant renting this house for the summer is a chemist who knows a fair amount about water treatment. So needless to say, this pool has become a bit of a science experiment, and has started many interesting discussions about pool chemistry. The other night, I was talking to him, and he brought up the idea of a dionizing resin. I had never heard mention of this, and I'm wondering why this isn't something used to remove Iron from pools. My guess is that it just gets too expensive, but for people with iron problems, pouring money into chemicals that don't really get rid of the iron can get pretty expensive as well.
So is there a reason deionizing resins won't work for pools?
