I've been adding Kalk to my top-off without fully understanding how it works.

I did a bunch of reading yesterday. One thing I read and thought was interesting is that the pH of Kalkwasser is 12.0 at saturation. For the fun of it, I took one of my 2 pH probes and stuck it in the top-off bucket. Sure enough, it shot up to 12 right after I stirred the mixture.

I'm still not sure if or how this will help much. For now I'm just monitoring it, but I may be able to use the pH of the top-off to somehow tell me when I need to stir the mixture or even add more Kalk to the bucket.

My coworker thinks I could use this to automate a pump to mix it for me.
