Calk drip in 6 gallon nano?

So i've read trough sk8rs post about using kalkwasser as auto top off. What im wondering though is if my topoff will raise the PH too much in such a small system.

My water level change about 1/2 to 1 inch inbetween "fillings" and the total water level is about 10 inches high.

It should not be a problem, but if you do see the Ph start to rise you can add one to two tablespoons of white vinegar to the Kalk solution which will lower the Ph and has the added benefit of allowing you to dislove more lime into the solution.

White vinegar as in food grade? Not sure what % is should have etc.
