Correct. It is important to make some minor programming changes to the system, other than that it is typically an easy switch. I would set the system efficiently and you will be just fine. A typical system in your application properly sized and designed will only use 1/4-1/2 bag of potassium chloride per month. The less water you use, the less salt... maybe look at your water consumption and see where you can lower it. I have installed automated faucets, ultra low flow toilets, high efficiency dish washer, laundry etc... and we are down to less than 20 Gallons per person per day excluding irrigation.
