How often do you dose MG?

Can some of you share how you dose MG?
Do you dose once a week? Once a day? Every 2 days? Continuously via dosing pump?
Thanks.
 
I really think it depends on how much your tank uses. I would dose to 420, after a week it was 350-370. I would dose with my water change.
 
I don't dose it ... After a gallon of Alk & Ca (usually takes a month) I dump a 16oz container of MG in my sump by my skimmer.

I seem to always have good MG levels doing it that way.
