Jura coffee maker filter and detergent

Hello Community,

I have now, after I had a Melitta Barista T coffee machine for years, treated myself to a Jura Z10 machine.

I now have pretty hard water in the house (23 degrees dH). With the machine came a Claris Smart water filter.

Are the water filters recommended for hard water ? I have now read several times that regular descaling is sufficient. Is then enough for this the machine interval when this displays descale, or more often ?

Furthermore, I wanted to ask if there is an alternative for the Jura milk system cleaner mini tablets that you use after each milk use or should you already use the Jura tablets ?

The following alternative products I find interesting, what do you say ?
(About product suggestions on your part I am open!)

For the cleaning tablets I thought of:

For descaling:

For the milk system:

However, I would not know with the milk system, how many milliliters I should take for a rinse, because 40-60 ml for 2l should be used.

10 ml ?? then per rinse ? maybe you have a tip ?

About a field report and feedback I would be happy, because here are also some long-time coffee experts with their own stores on the road .

Many greetings
Sven
