could be a batch that you got? Did you test it before dosing? I learned from my own experience there that I should test the newly mixed saltwater before I put it in, so I know what to dose safely.

I bought a big thing of magnesium dosing stuff, and I haven't even cracked it open yet because of where the Mg's at.

Good point! I always test my IO when I get a new batch, to ensure my mixing recipe stays the same.

Also, remember that magnesium (as is alk & calcium) go up proportionally to SG.
