Are salt water pools actually safer or can they still make you sick?

Read full question

Switched to a saltwater pool two years ago thinking it would be gentler on my family, but my daughter broke out in a rash after swimming last weekend and now I'm second-guessing everything. My neighbor swears her kids get ear infections from their salt pool too. Are saltwater pools actually safer than traditional chlorine, or have I been sold a myth?

Quick Answer

Salt water pools are typically healthier than traditional chlorine pools and rarely cause illness when properly maintained. However, poor water chemistry or contamination can lead to skin irritation, respiratory issues, or infections.

Are Salt Water Pools Actually Safer or Can They Still Make You Sick?

Understanding Salt Water Pool Health Benefits

Salt water pools produce chlorine through electrolysis at more stable levels than traditional pools. Key advantages include:

  • Gentler on skin and eyes
  • Reduced chloramine levels
  • Minimal chlorine odor
  • Softer water feel

Potential Health Risks

Causes of Pool-Related Illness

  • Improper chemical balance
  • Generator malfunction
  • High bather contamination

One common worry — that salt pools cause ear infections — isn't really supported by the science. The CDC describes swimmer's ear (otitis externa) as coming from water lingering in the ear canal, not from whether a pool is salt or chlorine, so a salt pool is no more (or less) likely to cause it than any other properly maintained pool.

Recommended Water Chemistry Parameters

ParameterTarget Range
Free Chlorinethe right level for your CYA (typically around 5-8 ppm once CYA is in the salt-pool range of 70-80)
pH7.2-7.6
Salt Level2700-3400 ppm
Cyanuric Acid70-80 ppm (Trouble Free Pool and SWG makers run salt pools higher than plain-chlorine pools; 60-90 acceptable)

Prevention Strategies

  • Test water chemistry 2-3 times weekly
  • Run generator 8-12 hours daily
  • Clean generator cell per manufacturer specifications (typically every 2-4 months depending on usage)
  • Shock treat when necessary

When to Seek Medical Attention

Consult healthcare provider if experiencing:

  • Persistent skin rashes
  • Severe respiratory symptoms
  • Prolonged gastrointestinal illness
  • Eye infections

For the full breakdown of safe chlorine levels by CYACyanuric Acid (stabilizer) — Sunscreen for your chlorine — it keeps sunlight from burning it off. The catch: the more you have, the more chlorine you need to keep. learn more → level, see our pool water chemistry guide.

Safety first: follow every product label and your equipment manual, wear protective gear (gloves and eye protection), and call a pro when a job is beyond you. safety details ↓Handling chemicals: never combine concentrated pool chemicals with each other (for example chlorine with acid, or two different chlorine products) — pre-mixing them in a bucket or container can release toxic gas or start a fire. Add each chemical to the pool separately, let it circulate before adding the next, and use a clean, dedicated scoop for each. When a label says to pre-dissolve, add the chemical to water, never water to the chemical.
