In a strongly lit well-planted tank or in aquariums with few fish a lack of macronutrients may occur, which in turn can lead to poor plant growth. Makro Basic Nitrat brings the important macronutrients of nitrogen and potassium into the tank. The plants can once again access plentiful resources, resulting in lush growth as an expression of gratitude.

Weekly water changes of 25 - 50% are recommendable. The dosage can be raised or lowered depending on the requirements. If the aquarium water shows high readings of nitrate from the start, this fertilizer is not suitable, though. It has been designed to prevent the accumulation of large concentrations of macronutrients. If high levels of nitrate occur, the dosage should be reduced.

The basic supply of macronutrients in a tank is provided either by our NPK fertilizer, the Estimative Index fertilizer or by single-nutrient fertilizers (Makro Basic Nitrat, Phosphat and Kalium). The aquatic plant fertilizer Aqua Rebell Makro Basic Nitrat is the most important component in the single-nutrient fertilizing system. It adds the essential nutrient of nitrogen to the aquarium and is also optimally suited for batch fertilization (larger fertilizer quantity given just once), for example after a waterchange. This is a very good way to achieve a water plant-friendly nitrate content of approx. 10 - 20 mg/l nitrate. Aqua Rebell Makro Basic Nitrat can of course be dosed by the day, too. Besides nitrogen, Makro Basic Nitrat also adds the important nutrient of potassium to the tank. Thus, Aqua Rebell Makro Basic Nitrat lays the foundation for healthy waterplant growth.
