Can I mix Mag with R.OD.I ?

[Gyarados]

Quick question here about magnesium.
I usually dose Red Sea supplement C- magnesium by hand, but got an idea.
I usually evaporate my full 5g Rodi reservoir; so can I mix magnesium into the auto top off water?
Like what I would dose in one week of mag and dump into the ATO?

You can do that. Might even be better than dosing a large amount at one time. If it were me I would put in a bit under and keep an eye on mag with testing and adjust.

Yes,that's fine, but unnecessary, IMO. Real magnesium depletion is hardly noticeable in a week, so once a week manual dosing is plenty often enough.

Thanks both for the advice!
