Dave understood your regeneration frequency. His point was to set the softener to 70% of its capacity. The capacity of the softener is based on the salt dose. If you can find in the instructions how to determine the capacity and set a salt dose then assume that if you use 200 gallons per day (national average daily usage is 100 gallons per day). Set the unit to give 16,000 grains of capacity. Thats less than 70% but will give a regeneration every 5 days. Plenty even if you use more than that. The unit will regenerate after 1000 gallons has been used. You might want to set it a little higher if you are planning a really big party with lots of “stay overs”.
