I bought 4 oz 99.3% KNO3 powered, to make liquid fertilizer for planted aquarium.
I use http://calc.petalphile.com/ for calculation.
4oz = 113.4 gram.
My goal is each 1ml fertilizer for each 5 gallon water to raise NO3 by 5 ppm. To get close to 113.4 gram, I got 734ml, which is 24.8oz. But I don't have that big size bottle. So I end up use 2oz the powered with 12.4 oz water solution.
The dose is 1ml for every 5 gallon water, which raise NO3 by 5ppm.
