    Natural protection against limescale with Seccua AntiCal

    Like many of our foods, our drinking water provides us daily with important minerals and trace elements. These include calcium and magnesium, minerals that are important for our metabolism and for the formation and preservation of our bones. But it is precisely these two substances that are responsible for water hardness and cause limescale deposits on pipes, in shower heads, and in water heaters.

    As long as water is deep in the ground, magnesium and calcium are stably dissolved in it. If it is then forced to the surface and transported through pipelines to our households, the pressure and temperature of the water change, and some of the previously stable magnesium and calcium solutes then combine with carbon dioxide in the water to become limescale crystals. This occurs primarily where there are already limescale crystals present, such as on pipe walls or in water heaters.

    The technology: stabilization of the limescale

    The Seccua AntiCal technology converts some of the hardness in the water to fine limescale crystals that are then suspended in the water and can no longer crystallize – or form classic limescale deposits – on the walls of pipes or water heaters.

    If the temperature or pressure in the water lines changes, most of the hardness will now tend to deposit on the fine crystals in the water instead of on the pipe wall, and the formation of limescale on surfaces will be sharply reduced.

    In this way, the Seccua AntiCal merely controls a natural process, namely limescale formation, and ensures that the limescale first and foremost precipitates on limescale crystals that were formed by the Seccua AntiCal and are now suspended in the water, instead of precipitating on surfaces such as pipes, water heaters, or shower heads.

    Technical Data about Seccua AntiCal

    Seccua AntiCal


    Seccua AntiCalⓇ Medium


    • reduces hardness measurable up to 20%
    • reduces scaling in water heaters, on pipe surfaces, in coffee-makers and alike equipment significantly
    • healthy minerals like calcium & magnesium are kept in water


    • The Seccua AntiCal(TM) medium has a typical lifetime of 5 to 10 years
    • Please assure that the water does not contain double-positively-charged ions like Fe(II) or Cu(II) when entering into the AntiCal(TM) media, since that will destroy the funtionality of the media

    Max. flow

    • When stand-alone: 15.9 gpm peak load
    • When combined: 7.9 gpm peak load

    Possible combinations

    Can be combined with Seccua AntiTox or Seccua AntiArsenic

    UrSpring, Seccua AntiCal, and Seccua BioFilter – an ideal trio

    Protection against limescale with Seccua AntiCal

    The Seccua AntiCal prevents new limescale from forming on the inner walls of your home’s water lines and even reduces existing limescale deposits. At the same time, the healthy minerals calcium and magnesium are retained in the water.

    Unlike traditional softening technologies, NO SODIUM is added to the water, as would be the case with a regular softener, and all minerals are NOT removed leaving the water in a corrosive state, as would be the case with reverse osmosis. The water remains healthy, and you can drink it or use it for washing or showering without hesitation.

    UrSpring: removing pathogens

    Our water experts recommend using UrSpring AntiCal in combination with a downstream UrSpring The UrSpring removes from the water all pathogens and all other germs that enter our domestic water lines by the billions each day from the municipal water supply.
