Question for you:
I have high iron. I put in a new system,along with the air injection tank as told by you with the air injection valve. I had emailed you a few weeks ago about still having an iron problem, you had told me to backwash more I have, I still have the same problem. my old system i didn't have this problem. I asked last time is there something more I should be adding to my mix tank?
Birm is very sensitive to low pH. A pH less than 7 degrades the Birm media, and can wear off the thin coating of manganese dioxide. At that point, it can filter out sediment, but will not remove dissolved iron from water.
