You can even call a specialist  to determine the amount of hardness in the water supplied to your area.


Some parts of the world have constant high temperatures throughout the year, such as the US Southern part. It means the chemicals such as chlorine added into the pool evaporates quickly. 

So, we will put more chemicals in the water to maintain its hygienic, but lead to higher calcium levels through chlorine. 

One way to prevent this is by investing in constructing a pool enclosure. It will prevent the direct rays of the sun from heating the pool and causing a chemical imbalance.
