The Truth About Mineral Pools

Himalayan Salt
Magnesium Flakes (Epsom Salt)

There are many different options on the market claiming to provide the ultimate mineral pool system. Once your remove the smoke and mirrors you can see there is a clear differentiation in minerals available. Quite often consumers aren’t told about the specific ingredients in what some manufactures refer to as ‘magnesium mineral salts’ or ‘magnesium flakes’. Instead consumers are sold the claims of how beneficial their product is. In fact, not many mineral pool manufacturers are upfront about their use of Epsom salts as a main ingredient. A quick Google search will reveal the truth.

Today we are going to provide you with a comprehensive differentiation in terms of Magnesium Flakes (Epsom Salts) and Himalayan salts used as the basis for mineral pool sanitation. It will blow your mind!

Full disclosure before we start! The Purapool Oxygen Minerale only uses Himalayan Salts.

Magnesium Flakes Containing Epsom Salt

Magnesium Flakes (Epsom Salts) have been around for years and they been used to ease achy muscles and support healthy fertilization of your garden.

Epsom salts are a source ingredient adopted by many mineral pool manufacturers in Australia selling magnesium flakes. However, it’s important to note that Epsom salt is not actually a salt, but rather a mineral that contains high levels of magnesium and sulphate. Magnesium sulphate is actually used to help coral calcify and grow in Aquaria.

These salts do not belong in your swimming pool. Firstly, Epsom Salts have many adverse impacts to the health of your pool. Secondly, they provide you with the illusion that your skin soft and smooth. We are going to break this down and explain in a little more detail as to why Epsom salts are bad for your swimming pool, and why this is nothing short of an illusion.

High Calcium Hardness Damages Your Pool

A healthy pool should run at 200 – 400ppm calcium hardness. However, many mineral pool systems test your hardness at up to 800ppm. Pool shops will test for both calcium hardness and magnesium hardness to achieve this result, and they will say that 70% of the hardness reading is magnesium hardness. However, calcium and magnesium both contribute to overall magnesium hardness. 

When you start exceeding 400ppm calcium hardness, over time you start to get calcium build up on your equipment and internal walls which left untreated can cause irreversible damage. In terms of the pool sanitation cell the build up reduces the effectiveness and longevity, therefore requiring a costly replacement.

High Calcium Hardness Causes an Illusion

As soon as you start pushing above 400ppm in calcium hardness your water goes harder. Therefore, when you get into the water you will not be able to get the creams off your hands and you will feel like its slippery. This slippery and ‘softer’ skin feeling is the hardness, not the ‘softness’ that is pitched by many companies.

These clever marketing strategies that your skin will be left soft is just that, a clever marketing strategy and a failure in the product offerings. It’s all based on the calcium levels of your pool being double the ideal levels!

Mineral Pools Containing Pure Himalayan Salt

Sourced from the foothills of the Himalayan Mountains, Himalayan salts is a true salt rich in elements and minerals, including sodium and chloride. It not onlly contains up to 83 minerals, but also just the right amount of Magne-C. Unlike Epsom salts (which is not really ‘salt’), the salt component of Himalayan salts come packed rich in anti-microbial, anti-fungal, and anti-bacterial properties.

Himalayan salts not only regulate muscle function, regulate nerve function, and provides magnesium properties to increase overall health, but they are kind to your swimming pool and the environment too.
