Limescale is the biggest enemy of high hydrogen concentrations: A limescale-encrusted water ionizer delivers measurably lower H₂ values and operates inefficiently. This section explains how to recognize limescale buildup, how to properly descale your water ionizer—whether a Kangen Enagic SD 501, K8, or other model—and why regular maintenance significantly extends the lifespan of your device. Karl Heinz Asenbaum and Yasin Akgün provide specific instructions and clarify whether limescale in drinking water is a health concern or beneficial.
Answer from Karl Heinz Asenbaum | Freshly decalcified, the water ionizer delivers high hydrogen concentrations. Hello Mr. D., yes, these results are correct. At least that's what I can say about the pot devices. The Titanion SE Ultra would have to deliver a lot more, unless it is calcified. Unfortunately I don't have one anymore and can't tell you exactly what it [...]
Limescale in water – healthy or harmful? One of the most frequent questions from our customers is: Is the limescale in my tap water healthy or harmful? The answer is more nuanced than most people suspect. Limescale in drinking water consists of the dissolved mineral salts calcium and magnesium – two essential minerals that our bodies need daily. Karl Heinz Asenbaum has […]

On February 1, 2007, the hardness ranges were adapted to European standards and the millimoles of total hardness per liter was replaced by the (from a chemical point of view nonsensical) millimoles of calcium carbonate per liter. Water supply companies will probably continue to publish the total hardness, but this is not required by law. The new hardness ranges hardly differ from […]
How often do I have to disinfect my water ionier? Disinfection is usually not necessary. Descaling with a warm citric acid solution is in itself a disinfection. For some applications, for example in commercial areas or in doctor's offices, it is definitely advisable to disinfect the spout by spraying and wiping with a 10% hydrogen peroxide solution. […]
Softening through ion exchange – better not, or set the hardness low (°dH8 to °dH10) please. Softening can reduce the pH value of the water to one or two pH values. And the water can also be “artificialized” with sodium (Na2+), replaced by calcium (Ca2+). A similar but good question came up here on December 2, 14: If you have a decalcification system in your house […]
With most ionizers, depending on the lime content and the flow and the selected ionization level, the flow at the outlet for the alkaline hydrogen water decreases in the first 1 - 12 months. Therefore, you should descale these ionizers every two to four months, depending on the lime content and use. We recommend regular descaling of all water ionizers every two to six months at the latest, [...]

After the last descaling at the beginning of October, Lydia only managed 1,7-1,8 l/min with the reducing screw fully turned on. Before it was over 2 liters and I always had to reduce something with the screw. I'm surprised and would perhaps have the descaling run through again. I don't have any other idea because the water pressure at the taps is not […]
