I keep my mag around 1400-1500 typically using the RedSea Mag Pro test, but also have done some ICP to confirm my battery of tests. Every once in a while I'll end up with a week of dosing mag to raise it back.

Stability is king, so long as your test keeps giving you the same number you can use it as a guide so long as its not to dramatically far off. For example my RedSea kit is always about 50-100ppm lower in mag readings then the ICP test.. Not enough to matter to baddly in this case so long as I keep trying to hold it around 1450.

I keep my Alk now a days between 7-9...
