The two nutrients are needed by the plants that are in the tank or aquarium. The elements that are available in the macronutrients are nitrogen, phosphorus, and potassium. Nitrogen is in the form of nitrate and ammonium. The plants require nitrogen for the growth of the stem and leaf and it is part of the chlorophyll needed by these aquarium plants.
Phosphorous entails the mix of potash and phosphorous pentoxide which forms the monopotassium phosphate. Phosphorous is essential for the flowering and fruiting of the plants in the tank. Potassium is responsible for strengthening the leaves, growing points, and roots. The other macronutrients like sulfur, calcium, and magnesium are not needed as much since they are found in tap water.
