Salt Water Calculator — Australia
Metric by default: kg, 20 kg bags, AU targets 3000–4000 mg/L. Check your cell manual.
Calculate Initial Salt Needed
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
