Why chlorine is still needed in a saltwater system?

Saltwater pools are not a pool system that is entirely free of chlorine as chlorine is still used in the sanitation process. 

Pool water is drawn into a salt chlorinator cell located in the pump room to generate chlorine through a process called electrolysis.

Salt is commonly known as sodium chloride (or NaCl), which is broken down or separated into chlorine which is then used to sanitise the pool.

Salt Water Pool Advantages

• Salt water pools are much gentler on the eyes and skin

• Research indicates that salt water systems may be safer than chlorine pools

• Salt water pools produce softer-feeling water

• Salt cells in a salt water system only produce chlorine as needed

• Require far less maintenance when compared to traditional chlorinated swimming pools

Disadvantages of Salt Water Pools

• Salt water pools require a larger initial investment

• more expensive than traditional pools

• More complex than traditional pools

• salt water pools often require experienced technicians even for minor problems

• Salt can cause damage to pool equipments

• Costs more in the long run than a chlorine pool

• Must check and clean cells in the generator two to four times per year

• Will need occasional shocking throughout the year

• Sticky hair and skin after swimming 

• Normally need to be run for 24 hours per day to produce sufficient levels of chlorine

• May need to occasionally have the chlorine levels manually adjusted
