Maintaining the Calcium Hardness in Swimming Pools

by Pool Builders on 05-17-2011 in Articles

Swimming pool water hardness is tested based on all of the elements that are present in the water such as calcium, sodium, magnesium, iron, and other elements. All of these elements should be on their proper level to maintain the desired softness of the water for a comfortable and healthy bath in your swimming pool.

Among these elements, calcium is usually used as the base reference for the hardness or softness of the pool water as it is also used as a reference in order to know the water chemistry on any swimming pool. The right level for calcium hardness should be around 150 - 250 ppm in order to prevent any water related problems as too low or too high level of calcium in swimming pools will definitely result to more problems in the future.

A good way to check and know if there are any amendments needed in your pool is by running a water test from time to time. This simple routine definitely saves effort and money by preventing further expenses on cleaning, repairs or replacements of the pool, facilities as well as the pool furniture around the swimming pool area. Always get a pool water checkup whenever you see signs of irregularity in the water of your swimming pool as these are early signs that something is not right on your pool.

Corrosion is what concerns most pool owners when the level of calcium hardness in their pool water is far too low than its required level. The water then becomes corrosive and will slowly eat up your metal railings, equipments, pump connections, pipe fittings, and pool furniture and even leave stains in between your pool tiles. This will leave your pool deteriorating due to the corrosion as you will notice etching on the pool surfaces. Although low calcium hardness is at least much preferable than having a higher level, it still is disastrous and should be given importance as soon as possible.

The solution for treating this problem is to add the exact amount of calcium chloride calculated on the calcium chloride calculator. The ideal way of pouring this element in your pool water is by dividing it into smaller parts rather than adding it as a whole. Usually calcium chloride solution is poured in three parts every four hours or as per instruction of a pool expert.

Higher level of calcium hardness usually results in the clogging of the filtration system of swimming pools as this element leaves a scale formation on the surface of the pool water. The best thing to do in case your pool water's calcium hardness is way too high for its required level is to replace the pool water with clean water or by adding a special product developed to keep the calcium from depositing out. If not treated, the result of this chemical when retained in the water is that it leaves a burning sensation in the eyes of the bathers as well as the annoying irritations caused on the skin.
