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 Phosphat adds the important macronutrient phosphate to 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 phosphate 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 phosphate occur, the dosage should be reduced.

The basic supply of macronutrients in a tank is provided either by our NPK fertilizer, our Estimative Index fertilizer or by our single-nutrient fertilizers (Makro Basic Nitrat, Phosphat and Kalium). Our aquatic plant fertilizer Aqua Rebell Makro Basic Phosphat is a very important component in our single-nutrient fertilizing system. It adds the essential nutrient phosphate to the aquarium and is also optimally suited for batch fertilization (larger fertilizer quantity given just once), for example after a waterchange. Phosphate is the trigger for waterplant growth and can be added specifically for increasing the growth rates of the plants. A decreased dosage of phosphate will help limiting these growth rates. Aqua Rebell Makro Basic Phosphat can of course be dosed daily, too. Aqua Rebell Makro Basic Phosphat is of utmost importance for healthy plant growth.
