• 5.2 g (1 teaspoons) Potassium monophosphate (KP04)
• 10.8 g (2 teaspoons) Magnesium sulphate (MgSO4)
• 1.8 g (0.3 or 1/3 teaspoon) Potassium sulphate (KSO4)

3 times a week add 10 ml for a 20 gallon tank. Or 1-2 ml daily. Or 15 ml twice a week. This will add 30 ppm nitrate a week to a tank with corresponding correct proportions for the other macronutrtients.
