I think , will be more safe at night ( low PH) , best on refuge , NOT direct on main tank, depended what kind of Kalka reactor ( stirr) you have, i love Deltec Stirr, i dose ONLY clear water . Do slow , monitor Alk.
A good PH probe and PH monitor help a lot, Bulk reef Supply have a great PH probe.

are you dripping kalk as your main alkalinity supplementation?

I have been yes I changed my dosing to not go off while lights are on and it seemed to help

if you been dripping the kalk for months and suddenly observed the swing in alk(lowering) then perhaps your alkalinity consumption rate went up.

I also use kalk as my main supplementation. I used the reef chemistry calculator to find out how much kalk is needed for .6dkh daily consumption for my system(3 liters of saturated kalk a day) Its been rock solid.

Of your were having issues either your Alk consumption rate went up or you other elements such as calcium or magnesium are out of whack and caused a shift.

I used to run kalk through my ato but it was never enough to keep up with demand, so I dosed 2 part and used that to control the swings.

vinegar will lower ph so using to saturate the kalk has a down side as well
