38 Gallon Mixed Reef Cube Newbie

Which salt are you currently using? Alk and Mag levels are actually okay, calc could be higher but it's not that bad either.

Wouldn't start dosing for a while until you've actually added majority of the corals. If not planning to do SPS, kalk would probably be the easiest for a tank you size in the beginning.

I keep a mixed reef on 29 gallon personally and been using kalk with ATO. My tank needs no more than 1 spoon per gallon.
