Pool sanitisers – salt, mineral, or chlorine-free?

Whilst the bulk of pool purification is taken care of by the filter, sanitisers add an extra level of cleanliness by removing bacteria and algae. The question now is; salt, mineral or chlorine-free?

 

Salt

Salt is the most popular form of chlorination. Easy to use and nice to swim in, the system converts sodium chloride (salt) to sodium hypochlorite (liquid chlorine) through a process of electrolysis to kill any germs in the pool. When combined with an automatic pH controller such as Viron eQuilibrium, this system ensures the day-to-day water balance of the pool.

Mineral

As an alternative to salt chlorination, a mineral blend can be used to treat the water. Typically magnesium-based, it has the same chlorinating effect as salt, however the water is softer. Swimming in magnesium also has potential health benefits such as muscle relaxation.

Chlorine-free

We have recently been installing Enviroswim units with great success. This system uses copper and silver plates to kill bacteria and algae, emulating fresh river water.
