Rock salt is actually unrefined mined salt and may contain large amounts of inorganic contaminants such as manganese, iron, nitrates, silicates, sulfates, calcium and heavy metals. These minerals can affect water clarity, dissolution rate, stain and scale potential and other important water balance factors. Rock salt also contains dirt and other insoluble matter. For both of these reasons, rock salt should never be used in swimming pools. Pool salt is mechanically evaporated salt, also called "food grade salt" is created by the forced evaporation of saturated salt brines under controlled conditions. It contains many of the same inorganic contaminants as rock salt, but at lower levels.
Sifto food grade salt is primarily a non-iodized salt, meaning it does not contain added iodine. However, some variations may exist, so it's always best to check the packaging for specific information regarding iodine content. If you're looking for iodine in your salt, consider using iodized salt instead.
