Are you keeping stony corals? If not there is no reason to raise your calcium levels. If you are keeping any type of coral I would slowly raise your salinity to 1.026. If you do have stony corals then I would add a tablespoon of white vinegar per per gallon of kalkwasser mix to lower your pH a little. The vinegar will also allow you to dissolve a little more kalk into your solution if the need arises.
