Iron (Fe) is highly related to the color performance of aquatic plants. During iron deficiency, new leaves will lose their color, even yellowing. To achieve a strong color, reduce Nitrogen (N) and Phosphorus (P) (slow growth rate)and increase Potassium (K) (improve photo-synthesis) to obtain the best color performance.

Direction: Tabs are to be dosed directly, please refer to the dosing table. For best color development, use the Nutrient Potassium (K). If deficiency symptoms (chlorosis/yellowing) appeared, double the dosage until the new leaves return to normal.
