Why choose a mineral pool?
Typically, you would choose a ‘mineral pool’ over a traditional ‘salt’ or non-salt pool for the therapeutic benefits provided by mineral pools that you just don’t get from traditional pools.
Mineral Pools are great to swim in! The water is soft, exceptionally clear & makes you feel relaxed after a swim.
What minerals are in a mineral pool?
There are many different mineral pool options on the market and each has a different “blend” of minerals. The most commonly used minerals are Magnesium, (usually present as Magnesium Chloride), Potassium (usually present as Potassium Chloride), Sodium (present as Sodium Chloride) as well as Borates (essentially soft, easily dissolvable salts).
While all system blends differ, one common element is Magnesium and there’s a good reason for that.
Magnesium is responsible for many important cellular processes in the body, it promotes energy and wellbeing plus it promotes soft and healthy skin and it can support detoxification. Magnesium helps reduce stress and, as it is absorbed into the muscles, it helps alleviate aches and pains in tired muscles. Professional athletes use magnesium/minerals to help with recovery & muscle rejuvenation.
Studies have proven that absorbing Magnesium chloride through the skin is one of the most effective ways for the body to maintain healthy levels of this important mineral which is the reason why mineral pools are fast becoming the norm.
Magnesium also promotes water clarity as do Borates which is also a water softening agent.
How does a mineral pool work?
A mineral pool works in the same way as a standard salt pool, using the process of electrolysis which is a technique that uses a direct electric current to drive a chemical reaction. In our case, the pool water is passed over an electrode (salt cell) and converts the chloride ions from the Magnesium, Potassium or Salt into chlorine to act as the sanitiser, which is required in every pool to keep algae & bacteria at bay.
Thinking that there is no need to have chlorine in the water and that the minerals are responsible for keeping the water sanitised is a common misconception. While beneficial, adding a supplementary sanitation option such as Ozone, Ioniser or UV, does not remove the need for chlorine, a consistent chlorine level in your pool will always be required.
In summary, so called ‘minerals pools’ differ to a typical salt or non salt pool in the fact they provide additional therapeutic and clarity enhancing benefits, but they do not replace the need for a sanitiser.
Minerals can be used in non-salt chlorinated pools and equally well in Spa’s where they would be even more effective.
What to look for when choosing your Mineral Pool
Firstly, what do you want from your mineral pool. If you’re looking to have lower levels of chlorine in the water, you would need to consider adding a Ozone or UV system to your sanitation equipment as a mineral pool does not act as a sanitiser on it’s own. While UV or Ozone do not replace chlorine they do allow you to run your chlorine at the lower end of the range more effectively as they boost the sanitising capabilities of your existing system.
Secondly, the blend of minerals, make sure you know what minerals are in the product you’re buying and why you want them. Some products will have multiple minerals while others just have Magnesium.
Lastly, testing the water. Mineral pools alter some elements of water balance, and you should check with your local pool shop that they understand this and they can conduct testing correctly. Often your local pool shop will stock one brand of minerals and understand that brand but not necessarily all systems on offer on the market so sticking with what they use may be a practical solution.
Always talk to your pool professional and find out the options that best suit your needs.
