calcium up up and away please.

I recommend Randy Holmes-Farley's two part recipe. You can use calcium chloride to increase calcium (more or less) independent of the alkalinity. You can use the "Reef Chemistry Calculator" (google it) to figure out how much of each part to use to reach your desired levels.

What salt are you using and how frequently are you doing water changes? Also, how much coral (and what type) do you have? Seems strange that your calc is low despite daily dosing in a fairly young tank.

For what it's worth, you're not that low and the tank is only a few months old. I'd take the slower path and see how things unfold than to stress a ton about having perfect water.
