Brigitte W.: Which calcium do you recommend for the calcium shaft of my water ionizer?
Pay attention to germ protection
The addition of calcium is necessary for very soft water, otherwise the alkaline active water will not be adequately buffered with water that is very low in minerals (< dH 5), which means that there is hardly any sufficient deacidification effect. Nowadays, however, not all continuous water ionizers have this Calcium shaft, but the calcium is already integrated into the filter cartridges and the amount is designed for the entire filter life. Calcium sulfite is usually used. Some manufacturers also buffer their filters with magnesium, which is also suitable as a hardness agent. The reason for not using the calcium shaft is mainly of a hygienic nature: Since the calcium shaft is located behind the filter in the direction of the water flow, there is no longer any protection against germs. If the customer also introduces germs when filling in the calcium, a biofilm can form there under unfavorable circumstances.[/bs_col][bs_col class="col-md-6"]I therefore generally recommend using a filter with hardness formers such as Use calcium or magnesium to fill calcium through the shaft. If you do, you should check regularly and while maintaining the greatest possible hygiene whether deposits have formed in the shaft and, if necessary, use disinfectants such as —> Anolyte remove.
Manufacturers usually offer coral calcium beads for calcium supply. These gradually dissolve in the water flowing through them. For water with a hardness of dH 15 or more, I did not observe any dissolution, even after a year.
Glycerol calcium and phosphoric calcium are also available, which also dissolve in harder water. However, I am not aware of any documentation about the usefulness or harmfulness of these variants, so I recommend the variant with coral calcium, which can be considered safe, since our domestic drinking water also contains coral calcium from the sediments of the ancient seas and our organism can be considered adapted to it.
