I have iron stains that have reappeared again.
I had used the ascorbic acid treatment and then added MetalFree by Natural Chemistry to remove the iron from the well water. (I did this last season with good results) It all worked great, but, after a few weeks now, I was raising slowly to shock level and at 10 ppm chlorine level, the horrible stains are back!
I have added a double maintenance dose of MetalFree and stopped the chlorine addition. Will this remove my stains or should I add more of the MetalFree? Do I have to start over with the stain treatments?
Thanks so much for your help
