Compliance & Safety

Some industrial or medical pool standards require reporting in percentage rather than ppm.

Actionable Steps

Math of Purity

Percentage is simply ppm divided by 10,000. 3,200 ppm is common for saltwater pools.

⚠️

Safety Warning: Seawater is about 3.5% salt (35,000 ppm)—your pool should be much less than that!

Pro-Tip

Most salt cells have a 'high salt' shutoff threshold at around 4,500 ppm (0.45%). If you exceed this, the cell will stop producing chlorine to protect its electronics.
