John, 2 lbs of Pot Carb with 1.75 lbs to make 1 gallon of water. 1 lbs = 457
g and 1 gallon = 3.8 l ( top of my head but close enough as it is just POT
OX). 

Mix you Pot Card into cool distilled water; about 1/2 your total volume.
SLOWLY  add your Ox Acid as it WILL BUBBLE!!!!.  Add to completion and top
off with water to make final volume.
