    Salt vs Salt

    so whats the difference between say regular food grade salt and what we buy to put in the pool? Is it just refined more and disolves better?

    The salt we put on the table has iodine added.

    Salt suitable for the pool must be 99.9% pure sodium chloride, no added anything.

    Food salt will also often have an anti caking additive like sodium silicoaluminate so that it does not clump.

    It's also got iodine, which can't be good for the pool!

    Solar Salt for water softeners, the crystals not the pellets works well also.

    Not all table salt has iodine. Personally I'd be worried about cost also.

    Table salt has anti-caking agents, so it pours freely, which can cause stains.
