Iron(Fe) is highly related to the color performance of aquatic plants. During iron deficiency, new leaves will lose their colour, 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.
Tabs are to be dosed directly, please refer to the dosing table. For best color development, use with Nutrient Potassium(K). If deficiency symptoms (chlorosis/yellowing) appeared, double the dosage until the new leaves return to normal.
