Um, I feel the need to add the fact that the # you achieve from the formula is in ml, IE millilitres. That's why I divided a litre by 1000 at the end
Just sayin' ...
Don't be takin' the # you acheive from the formula and think that when it gives you a number of, say, 12.14, it's telling you to add 12 litres of acid
It really means 12.14ml
That's less than a tablespoon dammit, so watch your dosing
