Do you add Mag with each H2O chng?

It makes sense to me that this would be the correct procedure but I have not read that this is normally done. Do you?

I dose whenever it's low. Water change or not... Just me though.

How often do you test mag?

Your salt mix should have the proper magnisium levels in it, so no, I do not add magnisium because of water changes. I do however need to regularly add magnisium to my system. I know just about how much to add, so I test about once every two weeks to be sure I'm on track.

I have a relatively new tank so we have been testing daily, but are now backing down to around 3x/week.
