You’ll find three main types on the shelf: rock salt, solar salt, and evaporated salt (aka pellet salt). Rock salt is the cheapest—like the bargain-bin option. It’s mined directly from underground, but it’s loaded with insoluble impurities that can gunk up your brine tank. Think of it as the fast-food burger of the salt world: it’ll do the job, but you’ll pay for the mess later.
Solar salt is a step up, created by letting seawater evaporate in the sun. It’s purer than rock salt, but still carries some sediment. And then we have evaporated salt—the premium, fluffy, white pellets that are 99.9% pure. This is your gold standard. Why? It dissolves cleanly, leaves almost no residue, and protects your softener’s inner workings like a velvet glove.
Why Purity Is Your Best Friend
Imagine you’re making a perfect cup of tea, but you accidentally drop a teaspoon of mud into it. Gross, right? That’s what impure salt does to your softener. The more pure the salt, the fewer “mud” particles clog your tank and valves. Less clogging means fewer repairs and a happier you.

Pro tip: look for salt labeled “extra coarse” or “pellet” for optimal dissolving. Avoid “fine” salt—it can bridge together in your tank, forming a crusty hard layer that stops water from flowing. Nobody wants a salt bridge, folks. It’s like a traffic jam for your water.
