Is there a handy way to calculate this? Say I have a 100 gallon tank that is 20 gallons low and has a 12% concentration. At what concentration do I mix the 20 gallons I'm adding to get it the 100 gallon tank back to 8%? Or a 30 gallon tank at 6% that is five gallons low, at what concentration should I mix the 5 gallons to get it up to 8% ? Sure would be nice to have a chart, or formula, but there's a lot of variables. We just kind of estimate, but I would like to be more precise. We have 10 different size tanks we are trying to regulate, trying to maintain 8% for all. What method do you use?
