Key Benefits & Target Deficiencies Delivers nitrogen, phosphoric acid, potash, magnesium, and triple-chelated iron for high plant uptake demands. Prevents nitrogen chlorosis, leaf pinholes, stunted growth, and pale new leaves. Invertebrate-safe formula contains no dangerous copper concentrations. Promotes vibrant pigmentation and lush foliage without fueling algae from imbalanced dosing. Dosing & Application Instructions Dose 3mL or 0.1 fluid ounces per 26 US gallons or 100 liters of total water volume daily using the included calibrated pump, which dispenses 1mL per press. Apply this recommended dosage consistently at any time of day for low-tech aquariums with active aquarium soil. Apply this recommended dosage daily for high-tech aquariums with high lighting and pressurized carbon dioxide. Perform a weekly thirty to fifty percent water change to maintain clear water and prevent parameter skew over time.
