Calzestab Eisenex is used to reduce the hardness of water. This formulation binds calcium and other inorganic particles to each other so that they no longer react with the additional chemistry added. It increases the efficiency of chemistry and technical equipment, protects the pool from the deposition of calcium crusts on the walls of the pool and in the circulation circuit.

- prevents the deposition of iron and limescale before precipitation begins
- protects against damage to water distribution and heat exchangers caused by corrosion
- protects the filter device and the circulation circuit against limescale
- significantly reduces the consumption of chemicals for water maintenance
