Do you have a water softener system?

We also have the Grünbeck!

We have a Biocat from Watercryst, belongs to the family of crystallizers and ensures larger lime crystals in the water that can be wiped away very easily. Refilling salt is unnecessary, sodium content is not affected. works great for us.

I am always glad that we have such soft water here and do not need such a system. Yesterday, I happened to check with our municipal utility to see the value in order to properly adjust the new dishwasher. It is 7.1 here. It's incredible when you look at the map of Germany and see how high the water hardness is in other regions... you in the south are not really envied!

One wonders why the softening is not done centrally at the waterworks and the cost passed on in the water price, instead of running the hard water through the entire infrastructure so that thousands of decentralized units are installed at the consumer's premises.

We have moderately hard water in the range of 12.5 dH. That's so-so. Still too soft for serious complaints or worth the investment, but it doesn’t exactly make you happy either.

One wonders why the softening is not already done centrally at the waterworks and the cost included in the water price, instead of running hard water through the entire infrastructure so that thousands of decentralized systems are installed at consumers' premises.

Central softening is already partially implemented in new waterworks. In our area, such a facility has just started operating. A heating engineer mentioned that some people might have problems with the old house installations. The attached lime scale often sealed old pipes, and if the layer breaks down over time, it could lead to leaks.

Belongs to the family of crystallizers and produces larger calcium crystals in the water

Now it dawns on me. Honeywell produced and sold something similar/the same until the early 2000s. The crystallization nuclei here are macroscopic polymer beads, in modern terms "micro-plastics." When the micro-plastics issue arose and the media took notice, Honeywell practically made the technology disappear from the market overnight. Now the whole thing is sold under "Bio"-cat. I see. Whether you want to add microplastics or salt to drinking water is up to each individual to decide. Both certainly work.
