In the past I had always added kalk to my fresh water when doing water changes. I was advised against that since it can affect the levels of the fresh water. What is the propper way to dose kalk? I was thinking about sucking out a gallon of tank water, adding kalk, letting it sit over night, then dripping it.
I have to do a top-off tomorrow night so it might be a good time.
