What are the effects of an unsuitable salt concentration in a pool?

An unsuitable salt concentration in a pool can have various consequences, depending on whether it is too low or too high. 

A salt concentration that is too low:

• Reduction in the effectiveness of the salt chlorination system: salt chlorination that is too low may lead to insufficient chlorine production by the water treatment system, which can compromise its ability to maintain clean, healthy water.
• Growth of algae and bacteria: a low salt concentration can create an environment that fosters the growth of algae and bacteria in the pool, which may cause cloudy water, green patches and an increase in risk to health.
• Irritation of the eyes and skin: an insufficient level of chlorine in the water due to a low salt concentration can cause irritation of the eyes and skin to swimmers.

A salt concentration that is too high:

• Water tasting of salt: an excessive salt concentration can make the water in the pool too salty, which results in an unpleasant taste for swimmers.
• Equipment corrosion: a high salt concentration can accelerate the corrosion of pool equipment, such as ladders, handrails, main drains and metal parts in the filtration system.
• Irritation of the eyes and skin: an excessive salt concentration can also cause irritation to the eyes and skin of swimmers.

A suitable salt concentration must be maintained in the pool to ensure effective water disinfection and a comfortable swimming experience, and to maximise the lifetime of the pool equipment.
