Health

• Store-bought chlorine can sometimes cause skin irritations, red eyes, and allergic reactions, which are less likely to occur with a saltwater pool.
  
  

Cosmetic Effects

• Anyone with blond or light red hair has experienced having his hair turn green after swimming in a chlorinated pool. With saltwater this does not happen.
  
  

Environmental Impact

• Some people believe saltwater pools are more environmentally friendly, since fewer artificial chemicals are needed to maintain them.
  
  

Wear and Tear

• Saltwater is harsher on the infrastructure of the pool and equipment than traditional chlorination. Thus repairs and replacement of parts will probably be more frequent.
  
  

Odor

• Saltwater is considered by many to have a more pleasant, more natural aroma compared to the chemical smell of store-bought chlorine.
