Pooldoc and Mbar are the metals gurus on the forum, but I do know that the metal removers don't actually remove the metal--they just put them back into suspension so that they don't stain your pool. So it's an ongoing process to keep the metal remover in the pool, and the pH and chlorine low so no staining happens. The other alternative (there are threads on this in the metals forum, too) is to run the water past a high chlorine source JUST before it hits the filter, so that the staining falls out on the filter instead of in your pool. I urge you to read through some of the threads in the metals forum, even if you have to log out to be able to see them, to get a better idea of what you're dealing with.

That being said, there's no reason why you can't swim in a pool with iron staining, provided the water is clean and the other levels are in line. Just depends on how picky you are about clear, blue pool water!!

There are a lot of people in your position, with Intex pools filled from wells, and we're trying to work out a solution--but it's still in the works for now....
