As time goes by, you will get a feel for what your tank needs and can dose without testing every time but only to spot check. But until that time, would only dose if a test result told me I should.
Here is a tip if you haven't already learned it. When it comes to Cal and Alk, a lot of people forget about Mag. Make sure your magnesium is around 1350 before you worry too much about calcium and alkalinity. The corals need that level of magnesium in order to make effective use of the other two. In addition, if mag levels are not right, it is very easy to set off an imbalance between the other two. When you have that imbalance, things don't work correctly, as in, no matter how much you dose alkalinity it doesn't seem to come up.
But unless you have a lot of corals that are demanding calcium, you shouldn't have to worry much and the salt mix should give you everything you need.
