Limewater increases Alkalinity?

I currently have a low calclium (340 PPm) and high alkalinity. My PH is
consistently 8.2 . I switched from using limewater to using kent liquid
calcium and stopped adding buffer to let the alkalinity drop. (which is
starting to happen.) I have been reading about the relationship of
limewater to alkalinity and while I have seen that it clearly increases PH,
the literature seems less clear about whether it contributes to alkalinity.
One article said it indirectly contributes to alkalinity (not sure what that
means). Bottom line. If I stop adding buffer and only add limewater, will
my alkalinity keep dropping?

Only if the amount of Kalk you are adding is not enough to keep up with your
tanks demand. Kalk adds calcium and alk in a balanced ratio. IOW, if you
manage to raise your calcium with it, your alk will have gone up as well.
And, if you are maintaining calcium levels with it, it's likely that your
alk will not go down.
