Raising calcium without affecting alkalinty

[AriMiko43]

Ok so I tested my water today and got these results.
Alk - 9.6 dkh
Cal - 350 ppm
Mag - 1350 ppm

I am currently dosing through a bubble magus doser 130 ml of alk and cal and 20 ml of mag a day on a 156 gallon reef. How do I raise my calcium without affecting my alk levels? I am using the brs two part kit for alk, cal and mag

Try raising your Mg levels...I keep my Mg high and always keeps my Ca and Alk in check.
