Hi from my recently dug shallow well I am getting rust staining on my toilet and an iron odor in my water. I know a water softener or iron filtration system is the best option. However is there a cartridge filter I can get for my rainfresh whole home inline filter that will reduce the iron levels for a temp. fix? I was thinking about trying the ceramic .3 micron cartridge with an actice carbon core - what are your thoughts? Thank you
