If you've ever wondered what would happen if you used pool salt in a water softener, we'll tell you. The short answer is: nothing good.
Using pool salt in a water softener can damage the unit and reduce its efficiency at softening water. Pool salt is made from smaller salt crystals than the salt used in a water softener. Pool salt breaks down fast. Breaks down fast. That means pool salt will dissolve much faster than your water softener is designed to handle. Too much salt disrupts the complex ion exchange that occurs at a specific rate under specific salt conditions. If your water softener system is flooded with too much salt, and too quickly, it simply won't work. You'll end up with salty water, corroded parts, and a buildup of salt and byproduct sludge.
In short, pool salt can make your water softener sick. So if you're wondering if you should use pool salt in your water softener, the answer is a definite no. Use water softening salt as recommended in your water softener owner's manual.
