Auto dosing magnesium

[Madonia]

Hey all. I’ve been auto dosing cal and alk, and manual dosing magnesium every few weeks. I want to start auto dosing mag at this point.

What proportion of mag do you dose in comparison to alk and ca?
Right now I dose about 10ml of alk and ca daily. Should I start with dosing 10ml of mag as well?

That is my diy. It is advised to dose the magnesium part at 1 mL per 6.2 mL of the calcium (or alk) part. That assumes you are using the sodium carbonate version.
