I want to switch to Randy's recipe 2 &1/4 cup cooked baking soda in a gallon of RODI water (Recipe #1, part 2 below) and have been using BRS liquid sodium bicarbonate. My question is how close are these mixtures? I currently dose 16 ML/day. His chart shows .5 ml/gal/day for a mixed tank which equates to 21.5 ML/day roughly for me (43 gallons). Thoughts for starting out?
