Your settings are not efficient in the slightest. You need to do some adjusting. There is no reason to run the softener at that high of a salt setting. Maximum salt usage setting for a residential application is 8 or maybe 9 pounds per cu. ft. According to you numbers, you are using twice as much salt as you should be.
Salt should be at 6# per Cu. ft, total of 9 pounds per regeneration, and the capacity should be set at 30K. Day override does not matter, but it is typically set at 14-30 days.
How many people in your house? What is the raw water hardness (use the Hach 5b).
Does the system feed anything it shouldnt? Pool, irrigation, etc, that would cause excessive salt usage. Is this for a strictly residential application or is there another use (home business etc.)?
