Per whatever. If it was a lake you might dose two tons of calcium 
carbonate and one ton of magnesium carbonate. If it was a cell-sized 
tank it might be two picogram of calcium carbonate and 1 picogram 
magnesium carbonate. It depends on the level you want to achieve. I just 
mixed the powder in a 2:1 ratio and added some of that mix until I got 
to the hardness I wanted.
