Salt Water Calculator — Australia

Metric by default: kg, 20 kg bags, AU targets 3000–4000 mg/L. Check your cell manual.

For new fills or drained pools, enter 0

AU: 3000–4000+ mg/L — check your cell manual. mg/L = ppm.

Salt Water Pool Basics

How Salt Systems Work

Salt (NaCl) → Electrolysis → Chlorine + Sodium Hypochlorite → Sanitization

Advantages

Softer water, no chlorine smell, consistent sanitization, less handling of chemicals

Considerations

Higher upfront cost, salt cells need replacement, potential for corrosion, pH tends to rise

Salt Level Guide

Below 2500 mg/LToo Low
3000–4000 mg/LIdeal Range
2700–2999 mg/LAcceptable
Above 4000 mg/LToo High
Above 6000 mg/LRisk of Damage

Maintenance Tips

  • • Test salt monthly with digital tester or strips
  • • Clean salt cell every 3 months (or per manufacturer)
  • • Maintain pH between 7.2-7.8 (salt pools tend to drift high)
  • • Keep stabilizer (CYA) between 30-50 mg/L
  • • Shock periodically with non-chlorine shock
  • • Add salt after heavy rain or significant water loss
