Choosing the Right Salt for Your Saltwater Pool: A Comprehensive Guide

Pool salt, also called sodium chloride, is the most commonly used salt for saltwater pools. It is the same type of salt used to season food, but it is typically sold in larger quantities for pool use. Pool salt is available in different grades, including solar salt, evaporated salt, and rock salt. Solar salt is harvested from evaporated seawater, evaporated salt is produced by evaporating brine from underground salt deposits, and rock salt is mined from underground salt formations. All of these types of salt can be used in saltwater pools, but solar salt and evaporated salt are the most commonly used.
