    When I try to calculate How much kno3 I'm going to add to my tank and when I select "Estimative index" as my target. It says "To reach your target of 7.5ppm NO3 you will need to add ..."

    In EI method isn't the N level needs to be arround 10 - 20 ppm ? Why it says 7.5 ppm ?

    Dose these levels 2-4 times a week for EI.

    That 7.5 ppm you dose per day, multiply by 2-3 (# times to dose per week) will yield you within the range of 10 - 20 ppm EI dosing ..
