Every six months, your brine tank needs a spa day. Unplug the unit, scoop out any leftover salt (wear gloves; it’s slimy), and scrub the inside with a mild soap solution and a sponge. Rinse thoroughly. Why? Because algae and bacteria love a damp, salty environment. If you see pink slime, that’s Serratia marcescens—harmless but gross.
While you’re down there, check the brine float. It should move up and down freely. If it’s stuck, your softener might regenerate at 3 AM when you’re dreaming of beaches, not brine. A quick wiggle now saves you a flooded basement later. (You’re welcome.)
