Bring up newly made up water to the appropriate levels (I recommend 10 , 1380, 430) and then you will find things are quite easy to maintain from there, especially with a fairly light load like you have.
From there you can use kalk or two part, it likely will not take much.

Instance ocean salt doesn't have low level of Cal or Mg. Maybe it did, but the levels are normal now. From a sticky in RC, it has the following numbers:
Instant Ocean (new) Ca:400 Alk:11 Mg:1350
My own tests (using ELOS Mg and Ca test kits) confirm the numbers (actually I got a little bit higher numbers but it might be just my testing technique.)
