    My aquarium is 300 liters. I want to keep a copper concentration of 0.07 ppm.

    My mix micro nutrients has 6% copper, how should I calculate? See what I'm doing. (I hope you understand my English)

    0.2 grams of the mix of micro-nutrients = 0.02 grams of copper (6%)

    0.02 grams of copper = 20 mg = 20 ppm Copper

    20 mg / 300 (tank volume) = 0.07 mg / l = 0.07 ppm

    My calculations are right?

    300L * 0.07 mg/L = 21 mg in total.

    6% from 350 mg is 21 mg. So you need 350 mg (0.35 gram) for a 300L not 0.2 gram.
