I was reading theplantedtank's EI article and it mentions a solution of 33grams of KNO3 for 250 distilled water. The dosing recommendation is to use 5mL of the solution per 50L of water. so if my tank is 300L, I need to put in 30mL (5mL x (300/50)) of the solution.
My confusion lies in the ppm that is put into the tank.
e.g.
using the dosing calculator on the same website, 33grams of KNO3 dissolved in 250mL of water equates to around 1.6ppm of nitrate per 1mL of the solution in a 50L tank. Since I need 30mL, 30mL x 1.62ppm/1mL = 48.6ppm in 1 dosing. And it seems I need to dose thrice a week so that'll be around 140ppm of nitrate/week.
According this article (http://www.ukaps.org/EI.htm), I only need 20ppm of nitrate per week.
maybe I'm misunderstanding how EI works?
thank you very much for the help
