Salt pebbles are sodium chloride (salt) in small, round pebble or tablet form, used for water softening and in salt-water swimming pool chlorinators. They dissolve evenly and progressively to prevent limescale, reduce detergent use, and maintain equipment health. High-purity salt pebbles are also used in the food industry and, in their pebble form, can be effective for de-icing and providing traction on icy surfaces.  
Uses of Salt Pebbles

 Water Softeners:
    They are added to water softener units to remove hardness minerals like calcium and magnesium from water, which helps prevent limescale buildup in appliances and fixtures. 

Salt Water Pools:
Salt pebbles are used in salt chlorinators to generate chlorine, maintaining water quality and clarity in salt-water swimming pools. 
De-icing:
Their pebble-like structure provides effective traction on icy surfaces, making them suitable for de-icing roads, walkways, and driveways. 
Food Industry:
The high-purity salt pebbles are used in various industrial and food processing applications. 

Benefits

    Limescale Prevention:
    Softened water from salt pebbles prevents the buildup of limescale in showers, water heaters, and dishwashers, extending appliance life and reducing maintenance. 

Increased Efficiency:
Softened water improves the efficiency of heating systems and hot water, and can reduce the amount of detergent needed for cleaning. 
Even Dissolution:
The smooth, rounded shape of salt pebbles ensures even and progressive dissolution, preventing undissolved salt from accumulating at the bottom of the water softener. 
Equipment Protection:
By reducing mineral buildup, they help preserve the longevity of pool equipment and water softener components.
