TEST PO4 allows the measurement of phosphate (PO4) concentration in aquarium water. It is essential when fertilizing the aquarium with various fertilizers. High phosphate concentrations can be harmful to fish, while their excess leads to uncontrolled algae growth. Based on the test indications, appropriate fertilizer doses can be selected to balance macronutrients in the water.
