#1. 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.hen 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.
