My ca is 446 and Alk 7.3
Nitrate typically are 0-5
Phosphate .02-.05
I use Hanna digital testers for everything
And when I do fw top offs I add All for Reef which is a balanced blend of calcium Alk, magnesium and trace elements all in one product
It doesn’t make large corrections if one thing is out of whack, but if you get everything right and add regularly it will replenish them equally and help you maintain stability
