Saltwater system (salt chlorine generator)
A system that makes chlorine from dissolved salt instead of you adding it — gentler water, lower chemical spend, higher upfront cost.
A saltwater pool isn't chlorine-free: a salt chlorine generator (SWG) splits dissolved salt to produce chlorine continuously, so the water feels softer and you handle far fewer chemicals. The cell costs more upfront (roughly $1,500–$2,500 installed) and needs replacement every 3–7 years, but ongoing chemical costs are lower than a traditional chlorine pool.
