Putting Kalk in the ATO?

[Myka]

Nothing has changed in my tank as far as equipment goes, but the humidity in the house is a tad higher, not much though.

I'm going to add Kalk+vinegar to my reef in the next while here because I'm dosing quite a lot and think Kalk would help keep the ions in balance a bit better, particularly keeping chloride down a bit. I'm going to dose as much Kalk as I can while keeping an eye on the pH and use the calcium and alkalinity dosing where the Kalk falls short. I'm going to use a doser for the Kalk.
