MASTERLINE II 500ml – Liquid Macronutrient Fertilizer for Planted Aquariums
MasterLine II 500ml is a complete liquid fertilizer that delivers all essential macronutrients for the healthy, vigorous growth of aquatic plants. It allows aquarists to dose macros separately from micros, providing better control and adaptability, especially in densely planted or fast-growing tanks.
Its concentrated formula includes nitrogen (0.81%), phosphorus (0.20%), potassium (4.8%), and magnesium (0.36%) in highly bioavailable forms. The recommended daily dose is 1 ml per 30 liters, delivering 1.2 ppm NO₃, 0.2 ppm PO₄, 1.6 ppm K, and 0.12 ppm Mg.
Safe for all aquarium inhabitants, including shrimp and invertebrates, MasterLine II is suitable for daily or weekly use. For optimal results, use in conjunction with MasterLine I (micronutrients) and MasterLine Carbo (liquid carbon). After water changes over 50%, apply a triple dose.
