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
| Parameter | Target Range |
|---|---|
| Free Chlorine | the right level for your CYA (typically around 5-8 ppm once CYA is in the salt-pool range of 70-80) |
| pH | 7.2-7.6 |
| Salt Level | 2700-3400 ppm |
| Cyanuric Acid | 70-80 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
Disclaimer: Always consult pool maintenance professionals and healthcare providers for personalized guidance.
