How Much Salt Do I Need To Add?
Calculating required salt level based on pool volume in litres (L)
Salt needed (kg) = (Required salt level / 1,000,000) x Pool Volume (L)
1 kg of salt in 1,000 litres of water raises the salt level by 1,000 ppm
Converting Cubic Metres (m3) to Litres (L)
1 Cubic Metre = 1,000 Litres or 1 Litre = 10 Cubic Centimetres (10 cm

)
Pool Volume in Litres = (Length x Width x Average Depth) x 1,000
If pool size = 10m long x 4m wide x average depth of 1.5m, the volume = 10 x 4 x 1.5 = 60m

60m

x 1,000 = 60,000L
