Saltwater vs Chlorine Pools: Complete Comparison

How Saltwater Pools Work

Saltwater pools still use chlorine — they just generate it on-site. A salt chlorine generator (SCG) converts dissolved salt (NaCl) into chlorine through electrolysis. You maintain salt at 2,700-3,400 ppm.

Cost Comparison

• Salt system upfront: $1,000-$2,500 for the generator
• Salt annual cost: $50-$100 in salt + $50-$100 in electricity
• Chlorine annual cost: $300-$800 in chemicals
• Salt cell replacement: $200-$800 every 3-7 years

Pros of Saltwater

• Softer feeling water
• Less chlorine smell and eye irritation
• Lower annual chemical costs
• More consistent chlorine levels

Cons of Saltwater

• Higher upfront cost
• Salt can corrode certain metals and stone
• Cell replacement adds long-term cost
• Still need to balance pH, TA, CH, CYA

Verdict

Saltwater saves money long-term and provides nicer-feeling water. Traditional chlorine is simpler and has lower upfront cost. Both require regular testing and maintenance.
