Are you currently dosing anything? Doing 10% weekly water change an increase your calc/alk/mag a decent amount just from your salt. I use a product called All-For-Reef which I dose and supplements Alk/Calc/Mag. Your Alk of 10dKh is currently in good range but your Calc is pretty low and would want that around 420ish.
