225 gallons of water used per day with 15gpg will need a 32 000 grain system set up for 24 000 grain capacity.

There are conditions that would create a need for a larger unit.

So what size of water softener offers 21 000 grains of total softening capacity. Then multiply that total by the number of days between regenerations.
