This fertilizer contains important macro-nutrients like nitrate, phosphate, and potassium that can help regulate levels and prevent the growth of unwanted algae.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eMacro-nutrient Fertilizers for Aquariums With or Without Low Fish Stocking\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eThe three main macro-nutrients, nitrogen (known as nitrate), phosphorus (known as phosphate), and potassium (known as K), are incredibly significant in aquariums. In normal, planted community aquariums, adding nitrogen and phosphorus is usually unnecessary as these substances are adequately provided through food and fish excretions. However, in demanding planted aquariums or aquascaping aquariums, the situation is different. These types of aquariums have a higher nutrient requirement, particularly for macro-nutrients. If there is no or low fish stocking, N or P deficiency can occur, and K deficiency is also possible, but less frequently. This is because potassium is always present in some quantity in tap water and is regularly introduced via complete iron fertilizers like Plant Care Pro. Therefore, it is essential to keep an eye on macro-nutrients and supplement them if necessary in demanding plant aquariums. It is crucial to maintain biological balance while using an NPK fertilizer. Plant Care NPK nutrient ratios are chosen to ensure all three macro-nutrients are equally absorbed by the plants. This way, even with long-term and regular use, there will be no deficiency or detrimental accumulation of individual nutrients. It is crucial to avoid nutrient imbalances as they usually result in algae problems.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eWhen to Use Plant Care NPK?\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eThe nutrient consumption of each aquarium is specific to the quantity and species of plants, animal stocking, feeding, water changes, and growth conditions. Factors such as light quantity, CO2 addition, and filter technology also play a role. To determine the required NPK addition, it is essential to assess each aquarium individually. Plant Care NPK should only be used when there is a real deficiency of macronutrients. It is recommended to measure nitrate and\/or phosphate content weekly and dose Plant Care NPK accordingly. Measuring the potassium content of the aquarium water is usually not necessary, as tap water plus Plant Care Pro and Plant Care NPK supply sufficient potassium. Overdosing potassium is hardly possible and is typically not harmful. However, significant overdosing of nitrate and phosphate can promote algae growth. Therefore, it is essential not to use Plant Care NPK without first measuring the nitrate and ideally also the phosphate content. Measuring the nitrate content alone will suffice in practice as a basis for deciding on NPK fertilization and dosage. Simple immersion tests, like the Dennerle WaterTest 6in1, can be used for this purpose.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eDosage and Application\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eMeasure and fertilize your aquarium regularly for a few weeks to notice a pattern in the values and the macronutrients needed.\u003c\/li\u003e \u003cli\u003eAdd a weekly dose of Plant Care NPK according to standard guidelines of 10 ml\/100 L\/week, which equates to adding 5 mg\/L nitrate, 0.4 mg\/L phosphate, and 2.5 mg\/L potassium.\u003c\/li\u003e \u003cli\u003eIf your tap water has high levels of nitrate or phosphate, avoid using Plant Care NPK to prevent nutrient imbalances.
