Alright, so I created a post about controllably raising nitrates. How do I go about creating a standard solution of ro water and sodium nitrate so that I can manually dose in my tank? So I'm needing to know how many grams of sodium Nitrate do I need to add to 1 liter of water? Please explain if possible. Then can someone please explain how many ml of this solution would be required to raise 120 gal of water by 1ppm of Nitrate?
