You have to use HEDP + the CuLator -- HEDP, to keep it dissolved, and CuLator to remove it.

On a related note, has anyone tried or had any luck with garden hose filters, specifically the ones designed for RVs?
What's worked have been home-grown arrangements that filtered AND simultaneously exposed the water to air. Most likely, until your water is exposed to air, the iron is dissolved, and won't be filtered by a closed RV unit. Now, if you aerate or chlorinate BEFORE it goes through the filter, that's a different story.
