The beauty of EI is just ignoring all of that. Dose, change water, done.

Parts per million (ppm), means how many liters of substance do you have per million liters of water. Or, how many mL of substance per million mL, which is the same as per 1000 Liters. Water weights one gram per mL, so you can also call that how many grams of substance per 1000 liters of water. Again, you can divide both of those by a thousand, and you get how many milligrams of substance per liter of water.

If you have a 100 liter tank and want 10 ppm of table salt in it, you convert 100 liters to a mass measurement (in your head), which is 100,000 grams. Ten ppm would require .1 grams of table salt, which is 100 milligrams. So, measure out 100 milligrams of salt and dump it into the 100 liters of water and you have 10 ppm of salt in the water.

Take two aspirin for the headache I caused....sorry about that.

Sorry for being so flippant before, but it was 4:31 AM. PPM is not a measurement really, it is a concentration or percentage. Parts/Million Parts. It is used instead of long decimal percentages (i.e. 1 ppm = .0001%). Don't feel inadequate, I've worked in the environmental field for 20 years and there are people with Masters degrees that have problems with it. LOL

Remember, you are not measuring anything absolute, it is all relative. So, 20 ppm of Nitrate becomes 10 ppm of nitrate if you double the water. As for how many ppm of Nitrate you get from mixing 10 grams in 100 ml of DI water, there are good online calculators. They will tell you how many ppm of nitrate your solution adds to your tank size. Then you just measure it out, it is additive. So, if 1 ml of your solution adds 1 ppm of nitrate, and you want to go from 10 to 15 ppm, add 5 ml.
