Ok, finally got my numbers with me to enter them onto this... I think the Iron content is mostly removed... I did the 5 Gallon Bucket/Poly-fil project to get rid of a lot of it. And not as much is appearing in the pump filter anymore. Below are the updated numbers from two days ago. Water inside the house is taken care of by the culligan system. I am adding 1 quart of Muriatic Acid twice a day currently. Could also use some guidance on Chlorine. Currently using regular clorox bleach.
