Okay, here’s a pro tip that feels a little rebellious. Set the hardness 2 to 4 points higher than your calculated number. Why? Because your softener’s efficiency can drop over time as resin beads get tired. A tiny buffer means you’ll never get a surprise hard water day.
It’s like adding an extra blanket to your bed on a cold night. A little insurance never hurt anyone. You use a tiny bit more salt, but you never wake up shivering from hard-water showers. Worth it.
And if you ever get confused, just remember: “Hardness” isn’t about how tough your water is. It’s just a math equation. A fun math equation (yes, I said fun). You’re in control of the robot. Go set that dial, and enjoy your silky-soft towels.
Now go test your water. I’ll wait. You’ve got this.
