micros
Micronutrients [m], as opposed to the three macronutrients (npk), are elements that are essential to healthy plant growth, but are only needed in trace amounts. Iron, boron, and manganese are only a few of the micronutrients that are necessary for plant growth, and without them plants will exhibit a variety of deficiency symptoms. A proprietary blend of micronutrients, pfertz micros is designed specifically for the needs of planted aquariums.
