I dissolved 30g of KNO3 in 420mL of RODI Water. How many mL of solution do I add to my 400L tank to raise NO3 by 5ppm?
I got 21.9mL but the online calculators are not confirming that..
(wrong) Math: 61.3% NO3 by mass gives 18.40g NO3 into 420mL. That is a concentration of 43.81g/L. To raise 400L 5ppm, 2g of KNO3 is needed.. 43.81/2=21.9? Pretty sure something is wrong in that last step..
