In a recent webinar Zimmer and Peacock discussed the suitability of ZP’s sensors for measuring the quality of swimmign pool water, we covered: pH, redox and chlorine.
- Liquid Chlorine (Sodium Hypochlorite)
- Poured directly into the pool or added through a chemical feeder.
- Quick-acting but degrades over time and requires frequent additions.
- Chlorine Tablets (Trichlor or Dichlor)
- Placed in floating dispensers, skimmers, or automatic chlorinators.
- Dissolves slowly, providing a steady chlorine release.
- Some contain stabilizer (cyanuric acid) to protect chlorine from sunlight.
- Chlorine Granules (Calcium Hypochlorite or Dichlor)
- Sprinkled directly into the pool or dissolved in water before adding.
- Used for daily chlorination or “shocking” (higher doses to break down contaminants).
- Saltwater Chlorination
- A saltwater generator (chlorinator) converts salt into chlorine through electrolysis.
- Provides a continuous, gentle chlorination process with lower chemical maintenance.
- Chlorine Gas (Commercial Use)
- Highly effective but dangerous; mostly used in large public pools with strict handling procedures.
