So what’s the best system? If you want true, spa-like soft water, go salt-based. The Fleck 5600SXT is the king. If you have mild water and hate buying salt, the SpringWell FutureSoft salt-free system is solid (pun intended).
Don’t overthink it. Test your water, pick a size, and hire a pro. In a week, you’ll be rubbing your hands together in the shower like a supervillain. Your dishes will sparkle. Your hair will do that thing. You’ll wonder why you waited so long.
Now go forth, my friend, and make your water behave. Cheers.
