Your water softener is basically a wizard in a metal box. It takes that nasty, hard water—full of calcium and magnesium—and swaps it for nice, soft sodium. This is a good thing. It means no more crusty shower heads, no more film on your glasses, and your skin will feel like a baby dolphin’s belly.
Don’t worry, you don’t need a chemistry degree. You just need to know a few simple steps. Think of it like feeding a very thirsty robot that lives in your garage.
