Nitrogen is so vital because it is a major component of chlorophyll, the compound by which plants use light energy to produce sugars from water and carbon dioxide (i.e., photosynthesis). It is also a major component of amino acids, the building blocks of proteins. Without proteins, plants wither and die.
Nitrogen in the shape of nitrate is an important nutrient for aquatic plants. … In densely planted aquariums or aquascapes, the nitrate consumption can get so high, that a nitrate fertilizer has to be added, to prevent deficiency symptoms and growth defects.
While ammonia and nitrite, another forms of nitrogen, are highly toxic to fish, nitrate is much less so. However, as nitrate accumulates, fish will eventually be affected. That’s why a weekly water change is highly recommended to reset the fertilizer concentration in your planted aquarium.
PHOSPHORUS (P) / (Phosphate)
The function of phosphorus in plants is very important. It helps a plant convert other nutrients into usable building blocks with which to grow. Phosphorus is one of the main three nutrients most commonly found in fertilizers and is the “P” in the NPK that is listed on fertilizers.
POTASSIUM (K)
Potassium is one of several elements that are vitally important to maintaining a vigorous level of growth in a planted aquarium. Potassium can become depleted in a rapidly growing system or when the source water has a low mineral content. In these cases potassium could become the limiting factor to growth. Pin holes in aquarium plants are a sign of potassium deficiency.
MAGNESIUM (Mg)
Magnesium is the central atom of the chlorophyll molecule, very much like the iron atom in the rather similarly structured hemoglobine (red bood pigment). Magnesium also fulfills many other functions in the organism of plants, e.g. in the activation of enzymes, the formation of proteins, DNA and RNA, carbohydrates, fats and vitamins, in phospate transportation, the carbohydrate metabolism and the transmission of energy.
MICRO
Micronutrients comprise chelated trace elements, made up of iron (Fe), manganese (Mn), copper (Cu), zinc (Zn), boron (B), and molybdenum (Mo).
Chelation is a way of keeping the micronutrients in solution and available to the plants that need them, instead of combining with other chemicals in the tank and becoming unavailable. Micronutrients are nutrients that plants need in trace amounts.
IRON AND POTASSIUM
Chelated Iron is utilized by plants to produce chlorophyll, a green pigment that helps plants to absorb light and make energy. In general, plants that are fast-growing or need bright lighting use lots of energy. In order to get more energy, they often require supplemental iron to produce an abundance of chlorophyll. Ther
