cory add some dolomite to your calcium reactor to raise mag levels and alk levels... set it and forget it..You'll have to use a ratio of 1:7 to 1:9 (dolomite to calcium media) in the reactor else your alk level may hit the roof. I use brightwells, and it works well..though i do have to use brs mag to raise it still.. constant battle unfortunatly for those who run kalk...
