Low Mag

[Myka]

I have yet to find a salt mix that has enough magnesium in it, although I hear the Reefer's Best does. Anyway, the Mg is probably that low because your salt mix is low, plus the inhabitants are using it up. Do like Tony suggests by increasing the Mg in the freshly mixed saltwater before the waterchange.

That's what I find wierd, should it have dropped to 400 in the first place? I'm keeping up Alk and Calc via waterchanges so it stands to reason that if Mag is depleted a lot slower it should be holding at around 700, no?
