Mineral pools vs. saltwater - what is the difference?

When deciding between a mineral pool system or a salt pool, it’s important to understand the differences. When we think of salt water, we usually direct our minds to healing bodies of water like the ocean, or Epsom salt baths after vigorous physical activity. But, although salt is in the name, it’s actually hard working minerals such as magnesium chloride and the choice of water oxidation technology that each mineral pool provider uses that are beneficial. 

Salt pools, on the other hand, use only sodium chloride to produce chlorine and to disinfect the pool. Salt pools do not produce the same salty taste of the sea, nor do they leave the same amount of residue on your skin – sea water has 35,000 ppm of salt while saltwater pools only have around 2500-8000 ppm. They both have their place, but it’s best to be informed about the functions of each when deciding on your new pool, or considering switching systems. 

Cost

Mineral pools have a marginally higher upfront cost. However, you will certainly recover this quickly with less ongoing monthly costs due to the reduced chemical usage compared to chlorine or salt pools. Saving you time, money and energy on a monthly basis. 

Water quality

The Theralux Complete Mineral Pool System, is self-oxidising (in fact, it is the most powerful oxidizer known in the entire swimming pool market!), releasing toxin free water, and therefore dramatically decreases the need for other water balancing chemicals, such as chlorine. The water quality is high and often has a ‘silky’ feel thanks to the ongoing cleanliness of the water. The minerals work with the water to maintain the pH level for longer with very little ongoing maintenance. Minerals pools also have high water quality thanks to magnesium being a natural flocculant.

Saltwater pools use a chlorine generator to keep the pool clean, but the chlorine is administered more consistently and is not as harsh on the skin as chlorine pools, this can also help reduce algae build up. Saltwater pools are not chlorine-free and so while the water quality is extremely clean, it is harsher than the mineral alternative. 

Pool protection

Mineral pools – especially those that use AOP – are easier to maintain, gentle and won’t be as prone to corroding the pool and pool accessories, so you can maintain the quality of your pool water without sacrificing the pool itself. 

Saltwater does not mean your pool will crumble over time, however with higher concentrated salt pool, it may take some work to ensure its naturally corrosive nature won’t deteriorate the pool. You’ll need to be on top of maintenance and keeping commonly affected areas like concrete and metal components clean and protected. 

Skin saving

Mineral pools are the best option for anyone who suffers from skin irritations or allergies. Although saltwater pools are gentler than chlorine pools, those that use higher salt levels are still are associated with skin flaring for sensitive skin and, even if you don’t have easily irritated skin, it can still dry it out. While the clarity of the water in both options is quite similar, water quality is far superior in a mineral pool, especially one featuring AOP.
