Thank you for your response. The gpm is .50 so I assume that's about 14 lbs of salt per regen. I already did use 1 cup of super iron out diluted in water with a regen last night. The iron test before I put in the softener was 3ppm and the hardness slightly hard. I set the setting of 17grains of hardness on the fleck. After I used super iron out the same thing happened after the regen-light yellowish water for about 10 to 20 gallons then it was crystal clear.
( like I said in previous post I noticed on Tuesday the brine tank was out of salt so added 2 bags at 5pm then regen at 8pm then on weds night I did another regen so that the new salt had 24 hrs to sit in the water and used super iron out).
Brine refill is 7 minutes at 0.5 GPM is 3.5 gallons. At 3 pounds of salt per gallon of water, you are using 10.5 pounds of salt.
From that page from Gary S, just your
iron alone would be treated as if it were 4*4=16 grains of hardness. So if you actually had 17 grains of hardness and no manganese etc, you would have to apply salt as if you had 33 grains of hardness.
You really should go through the link, and the calculator at

One of the things you should probably change in your 5600sxt also is Unit Capacity (Display Code C). That way your demand-based regen will be sooner if you down-rate the capacity as you probably should, and as you will probably conclude after working through those pages. That will let you save some salt vs going to a higher dose of salt each time.
