Added value
Knowing the amount of calcium and magnesium salts present in water and controlling it will improve the quality of life of water consumers, extend the life of household appliances, make personal hygiene or washing clothes more pleasant, using less soap and achieving better results.
Tips for use
The hardness of water intended for human consumption will depend on the area where it is located, as it is related to the type of rocks found in the ground where the water flows. Knowing this hardness will influence the quality of the drinking water we consume.
Calcium hardness is much more difficult to decrease than to increase. The following list shows some methods to deal with high levels of calcium hardness.
1. Replace existing water with new water containing little or no calcium hardness
2. Compensate for calcium hardness levels by lowering pH and alkalinity.
3. Decalcify the water.
4. Use a sequestering agent to help keep calcium in solution.
Hard water
In chemistry, hard water is water that has a hardness of more than 120 mg CaCO3/l. This means that it contains a high level of minerals, in particular magnesium and calcium salts. These are the cause of water hardness, and the degree of hardness is directly proportional to the concentration of metallic salts.
Hard water can be made soft again by the addition of sodium or potassium carbonate to precipitate it as carbonate salts, or by ion exchange with brine in the presence of zeolite or synthetic resins.
what is hard water?
Older generations have coined the phrase "hard water" because it makes cleaning difficult. The difficulty in cleaning is due to the calcium and magnesium compounds it contains. Freshwater sources usually contain varying amounts of calcium and magnesium. Water dissolves, suspends, or exchanges trace compounds and elements from the many things it comes into contact with.
Total water hardness is the measure of the total concentration of calcium and magnesium, the two most frequent bivalent metal ions, although in some geographic locations iron, aluminium and magnesium are also present at elevated levels.
Types of hardness
Water hardness has a shared distinction between temporary (or carbonate) hardness and permanent (or non-carbonate) hardness.
Temporary hardness is produced by carbonates and can be removed by boiling water or by the addition of lime (calcium oxide). While permanent hardness cannot be removed by boiling water, it is usually caused by the presence of calcium and magnesium sulphate or chlorides in the water, which become more soluble as the temperature rises.
Health problems
Some studies have shown that there is a weak inverse relationship between water hardness and cardiovascular disease in men above the level of 170 mg of calcium carbonate per litre in water. The World Health Organisation has reviewed the evidence and concluded that the data were inadequate to allow a recommendation for a hardness level.

Utilizo el producto para el uso indicado y lo recomiendo a quien tenga dudas del nivel de cal en el agua de su piscina. He comparado con otra marca que vengo usando y ambos dan resultados similare, osea calidad adecuada.
