Salt water vs Chlorine
Salt water pools generate chlorine on demand from dissolved salt (2,700–3,400 ppm), while chlorine pools rely on direct chemical addition. The water chemistry, equipment, and maintenance routines differ substantially.

How they stack up.
| Dimension | Salt water | Chlorine |
|---|---|---|
| Initial install cost | $1,500–$2,800 for cell + install; $200–$400 initial salt | Standard chemical feeder; minimal install |
| Monthly maintenance | Cell check + monthly water test | Weekly chemical adds + water test |
| Water feel | Softer on skin, no chemical smell | Standard chlorine feel, possible chemical smell |
| Equipment corrosion risk | Higher; salt mist affects metal fixtures | Lower; no salt exposure |
| Cell lifespan | 3–7 years; replacement $500–$1,200 | N/A — no cell |
| Coastal home suitability | Compatible with coastal-grade hardware | Standard hardware acceptable |
Salt is the right choice for swimmers with sensitive skin, homeowners who want lower monthly maintenance burden, and pools that will be in service long enough to amortize the cell replacement cycle.
Chlorine remains the right choice for older equipment pads that can't easily accept a salt cell, for homeowners who prefer simpler equipment, and for pools where coastal corrosion concerns make salt impractical.
