Plant Care NPK

The three macronutrients N = nitrogen (nitrate), P = phosphorus (phosphate) and K = potassium are particularly important. The addition of N and P is generally not necessary in normal, planted community aquariums, as these substances enter the aquarium in sufficient or sometimes even excessive amounts via the food and fish excrement. The situation is different with demanding plant aquariums or aquascaping aquariums, however. They have an above-average nutrient requirement, especially for macronutrients. In these types of aquariums, an N or P deficiency can quickly occur, especially with no or few fish. A K deficiency is also possible, but less common, as potassium is always present in certain quantities in tap water and is regularly added via iron fertilizers such as Plant Care Pro. In demanding plant aquariums, it is therefore very useful to keep an eye on the macronutrients and supplement them if necessary. The biological balance of nutrients is particularly important for an NPK fertilizer. The nutrient ratios in Plant Care NPK were chosen so that all three macronutrients are absorbed by the plants in equal proportions. This means that even with long-term, regular use, there can be no deficiencies or disadvantageous accumulations of individual nutrients. Nutrient imbalances should always be avoided, as they usually lead to algae problems.
