I think it would depend how you keep your calcium and alk in check. Some calcium additives contain magnesium as well, or if you just keep up with water changes it should be ok too.

I use brs two part system so even if when my calcium and alk are in check sometimes my magnesium is low so I have to add some of the mag solution
