A saltwater pool uses a salt chlorine generator.
This means that instead of adding chlorine to the pool water, you add salt, and the generator converts it to a form of chlorine to disinfect the water. It’s called a saltwater pool due to adding salt to the chlorine generator water at a level high enough to allow the machine to function.
Primary advantages of a saltwater pool:
Clear, smooth water
Lower annual cost
No chlorine smell
Gentle on skin and eyes
