How to choose the right salt for swimming pool?
Why choose salt that meets the EN 16401 standard?
To meet the requirements of pool electrolysis, the salt must be of very high chemical purity (with a sodium chloride content of over 99.9%), and have a low concentration of calcium and magnesium.
It is therefore important to use the right salt, as not all salts are created equal.
Our swimming pool salts comply with the European standard EN 16401 – Grade A, which specifies the composition, purity and moisture content that swimming pool salt must meet:
• The salt must have a purity of at least 99.4% NaCl (sodium chloride)
• Maximum concentration limits are set for certain metals such as copper, iron and manganese
• The salt must not contain any additives, such as anti-caking agents, which are often used in table salt to prevent it from recrystallising into salt lumps.
Failure to comply with this standard may reduce the service life of the electrodes and cause permanent stains on the pool surfaces.
The benefits of multi-purpose tablets
Multi-purpose tablets are available which, in addition to their salt function, also provide limescale prevention and corrosion protection.
The limescale prevention function makes it easier to maintain your swimming pool. Pool water naturally contains calcium ions responsible for limescale formation. This limescale builds up on electrodes, sealing components and pool surfaces (particularly at the waterline or on tile joints). AquaSwim Acti+ contains an anti-limescale agent that binds calcium ions to prevent them from forming deposits.
The anti-corrosion function helps protect metal parts. Pool water can be a source of corrosion, which causes damage to metal pool equipment. The oxides released in this way can settle on the linings (liners, polyester shells, etc.) and cause the formation of permanent stains, such as rust.
