I am looking for a good equation that I can use to calculate the amount of "stuff" I put in my tank like magnesium and calcium etc. I know where to find the calculator online, but thats really easy. I want to do the math. For instance. I want to raise my Magnesium by 130ppm and my system is 72 gallons total. Directions state that 1.5mL per gallon will raise mag levels by approx 15ppm.
Anyone know a good formula?
