Seachem Flourish Iron Plant Supplement – 100mL
Seachem Flourish Iron is a highly concentrated iron supplement for freshwater planted aquariums. It provides iron in a ferrous gluconate form, which is well suited for aquatic plant uptake and can help support healthy growth, stronger coloration, and improved plant vitality.
Iron is especially important for plants showing signs of deficiency, such as yellowing new growth, pale leaves, or short, thin stems. Flourish Iron is a great addition to planted aquariums where iron demand is higher due to strong lighting, CO₂ use, fast-growing plants, or heavy plant mass.
