CA/ALK/PH and MG questions

[Denis]

Yes, that's the old method that leads to buildup of sulfate.
Look at this new one : http://reefkeeping.com/issues/2006-02/rhf/index.php

I'm still looking for that MgCl , food grade is too expensive (5kg @ $95.40).
Any one knows where to get Mag Flakes (by DOW) ?
