I suggest you do a manual regeneration after adding 2 gallons of water to the water in the brine well in the salt tank; not through the salt. Let it sit for two hours, then do the manual regen. A good time to do that is on your way to bed.
Next morning, as soon as you get up, dissolve a 1/2 cup (dry measure) of Iron Out or Super IO to 2 gals of warmish water and pour it down into the water in the salt tank, wait 2 hrs, then manually regenerate it.
When done, add 1/3 cup liquid measure of nonscented bleach to 2 gallons of water, pour it into the water in the salt tank, wait 2 hrs and do a manual regeneration.
You can use water during the 2 hr waits but not during a regeneration.
