How Much Chlorine to Add to a Pool

Adding the right amount of chlorine ensures clean and safe pool water.

General Guidelines for Adding Chlorine

1. Determine Pool Size
   • Measure the pool’s volume in litres or gallons.
   • Example: A 50,000-litre pool needs about 200 grams of chlorine.
2. Check Chlorine Levels
   • Use a pool testing kit to measure free chlorine levels.
   • Ideal range: 1–3 parts per million (ppm).
3. Add Chlorine Safely
   • Dissolve chlorine granules in water before adding.
   • For tablets, use a chlorine dispenser.
4. Adjust Dosage as Needed
   • Add extra chlorine after heavy use or rain.
