Water Hardener (Calcium chloride) is a chemical compound used to maintain healthy water. Water can be ‘hard’ or ‘soft’ depending on the dissolved mineral content. If the calcium hardness level is too low, this can cause etching of plaster and metal corrosion. If the calcium hardness level is too high, this can cause scale formation, marble discolouration or cloudy water.


  • Softens the water
  • Protects equipment from corrosion
  • Good for our bodies, leaving skin soft and smooth

Dosage:  250g per 1,000 litres every time you fill your spa with fresh water.
