Seachem Flourish Iron 250ml | Iron Supplement for Planted Aquariums

Boost plant color and growth with Seachem Flourish Iron 250ml

Seachem Flourish Iron 250ml is a highly concentrated micronutrient designed specifically for freshwater planted aquariums. When added as part of a regular nutrient routine, this iron supplement helps iron become available to plant tissues, supporting deeper greens, bolder new growth, and a more natural look across a variety of aquatic plant species. The compact 250ml bottle is designed for long-term use in hobbyist setups, delivering small, steady doses that fit into routine weekly maintenance without requiring major changes to your existing care plan.

In practice, plant color and growth in a planted tank fluctuate with lighting, substrate, and other trace elements. Flourish Iron is designed to work alongside your routine fertilization, offering a predictable source of iron that can help maintain vibrant color without shifting water chemistry dramatically when used as directed. For tanks that experience seasonal lighting changes or new plant introductions, regular dosing can help emerging leaves show brighter color and steadier growth.

Key benefits

• Concentrated iron supports vivid leaf color and sturdy, new growth across a diverse set of freshwater aquatic plants

How to use

• Follow label directions for dosing frequency and amount; measure with a clean dropper and distribute evenly across the tank
• Dose during routine maintenance or after adding new plants or after pruning, when uptake is likely higher
• Watch plant response over the next 1–2 weeks; adjust cautiously if color or growth changes are desired
• If you use other iron products or fertilizers, consider compatibility and avoid overdosing to protect fish

Tips for best results

• Pair Flourish Iron with appropriate lighting and a balanced macro nutrient plan for vibrant color and healthy growth
• Schedule regular water changes to maintain trace element balance and prevent buildup
• Record tank conditions and plant responses to tailor future dosing to your setup

Note that results vary with plant species, lighting, and overall tank management; Flourish Iron is a tool to explore color and growth potential, not a guaranteed outcome.
