BF McUmber Posted April 18, 2021 Share Posted April 18, 2021 (edited) Today, I had to titrate my tap water with RO water to get to recommended harnesses... and then I went down the rabbit hole. Now I'm confused. I'm looking at my easy green and am confused how mathematically I convert the bottle contents into an ending ppm when added to a barren aquarium. Assume I am adding 1ml into 10 gallons of water for simple math. Using Nitrogen as example, easy green has 2.66% water soluble nitrogen. So for the fertilizer itself, converting from percent to ppm we would have 2.66*1000000/100=26600ppm Then putting 1ml of this into 10 gallons (37854ml). 26600*1/37854=0.7ppm (edit for 10 gallon) So even if this all went to nitrates it would only raise it by 0.7 ppm. I feel like when starting my tank (8 gallons-->0.88ppm) two pumps of easy green got me from like 5ppm to 20ppm when I was testing. What am I conceptually missing?
