First some basic background of my situation; I had my house re-plumbed in Oct of 2011 with all new PEX plumbing, water fixtures, toilets, tubs, water sofetner, hot water heater, etc. The only thing I did not replace was the pressure tank because it looked like it had recently been replaced. The water softener is a Fleck SXT 1.5 48,000 with a turbulator. My family is 3 adults 2 toddlers. House has 2 full bathrooms.
After 10 months of use I am starting to see signs of iron in the back of the toilets and on the new white tub (orangish tint) and the tests confirm with the untreated water reading 29 gpg of hardness and 2.2 ppm of iron. The treated water reading is 1 gpg of hardness and .7 ppm of iron.
Although the softener is taking a lot of the iron out, is it possible to reduce that even further ?
I have the DO set to 5 days, BD=60, BF=15, BW=15, RR=5. Hardness is set at 40
