How do you fix rust in your well water?

You should have used an iron sequestering agent if you were aware of the iron in the water. Filtering 24/7 until you have run the entire body of water thru the filter at least once.- called turn over. You must use the sequestering agent on a regular basis for this problem. Back wash the filter after 2 days of filtering and start with fresh filter media. DO NOT add chlorine especially liquid to the pool immediately after adding fill water. wait until you are sure that you have filtered for at least 6 to 8 hrs. k
