Putting Kalk in the ATO?

[Son Of Skyline]

I also use a JBJ ato which automatically stops running after a few minutes if the float valve gets stuck. This prevents kalk disaster. I do get varying evap rates throughout the seasons but I find that I don't get any KH changes using a lower concentration of kalk. My ca reactor is doing most of the work anyways and the kalk is just keeping my levels rock solid.

I just dump the kalk in and forget about it.
