Seachem Flourish Iron

Iron is an essential micronutrient that plays a critical role in chlorophyll synthesis and vibrant leaf colouration. Seachem Flourish Iron delivers a highly concentrated, 10,000 mg/L solution of ferrous (Fe²⁺) iron—the preferred form for rapid plant uptake. This ensures your aquatic plants get the iron they need for lush, healthy growth without relying on less available forms found in some fertilisers.

Iron deficiencies often show as yellowing (chlorosis) in new leaves and slow plant growth. Flourish Iron provides a safe and efficient way to prevent these issues, especially in tanks with fast-growing or iron-hungry plants such as stem plants and red species.

• Supplies bioavailable ferrous iron for quick absorptio
• Prevents chlorosis and enhances red plant colouration
• Safe for fish, shrimp, and all aquarium life
• Ideal for heavily planted or high-light aquariums

How to use 

Use 1 capful (5 mL) for each 200 L (50 US gallons) or as required to maintain about 0.10 mg/L iron. For smaller doses please note that each cap thread is about 1 mL. Use as needed to combat signs of iron deficiency (usually seen in new growth) which include: chlorosis (yellowing) of tissue between veins and short and slender stems.

Directions: Dose as recommended based on plant density and iron demand. Use alongside a complete fertilization routine for best results.
