Despite being busy with my day job and family I was able to find some time to write another article:
I wanted to write that article for a while and it grew much larger than I thought it would. In addition to information that has already been published elsewhere I also added a short section about reading German water reports.
Now I only have to write a water chemistry article that pulls it all together.
Cheers,
Kai
BTW: I thought I already posted this earlier but I could not find such a post by me.
