Seachem Flourish Iron is a highly concentrated (10,000 mg/L) ferrous gluconate supplement designed to address iron deficiency in planted aquariums. Iron is a critical component for chlorophyll production and metabolic processes in aquatic plants. Unlike EDTA-iron supplements, which utilize ferric iron Fe, Flourish Iron provides iron in the ferrous form Fe, which is much more easily absorbed and utilized by plants without the energy-intensive conversion process.
Flourish Iron is engineered to deliver rapid results, specifically targeting the health and pigmentation of high-demand aquatic species.
Bio-Available Ferrous Iron: Provides iron in the preferred Fe state, ensuring immediate uptake through both leaves and roots.
Enhances Red Pigmentation: Essential for bringing out the brilliant reds and purples in species like Ludwigia, Alternanthera, and Rotala.
Prevents Chlorosis: Effectively treats "iron chlorosis," characterized by yellowing leaves with green veins and spindly, pale new growth.
Complexed Gluconate: The iron is complexed with gluconate, which not only stabilizes the iron but also provides a small source of metabolic energy for the plants.
Safe for Invertebrates: Formulated to be completely safe for use in shrimp tanks and with all freshwater fish when used as directed.
How often should I use Seachem Flourish Iron?
Use 5 mL (1 capful) for every 200 L (50 US gallons) or as needed to maintain approximately 0.10 mg/L iron. In high-tech tanks with high light and $CO_2$, daily dosing may be required.
How do I know if my plants need more iron?
Look for signs of "interveinal chlorosis," where the newer leaves appear pale or yellow while the veins remain green. Short, stunted stems are also a common indicator of iron depletion.
Can I use this with Seachem Flourish?
Yes! Seachem Flourish contains a small amount of iron, but for tanks with many fast-growing or red plants, Flourish Iron is necessary to provide a dedicated, higher-concentration boost.
Seachem Flourish: The comprehensive micro-nutrient supplement to provide the baseline minerals that work alongside Flourish Iron.
Seachem Flourish Potassium: Essential for preventing pinholes in leaves, ensuring your plants are healthy enough to utilize the added iron.
Seachem MultiTest Iron: A high-precision test kit specifically designed to measure both chelated and ionic iron levels in your aquarium.
