Metric by default: metres in, litres out. Salt targets 2700–3400 mg/L.

Step 1: Choose shape

UK quick checks

  • • 7.5 × 4.5 m × 1.5 m ≈ 50,000 L
  • • 1 m³ = 1,000 L exactly
  • • Measure waterline, not wall top
  • • Salt target UK: 2700–3400 mg/L (max 4000)

Next: dose by litres

Use litres in chlorine and salt calculators. Add ⅔, retest, top up.
