Seachem Flourish Iron 250ml

Seachem Flourish Iron is specifically formulated to provide an optimal source of ferrous iron (Fe+2) for the healthy growth of aquatic plants in planted freshwater aquariums. Iron is a crucial micronutrient for photosynthesis and is particularly vital for plants that display red or vibrant hues, which often have higher iron requirements than green plants. The ferrous iron in this product remains bioavailable to plants for a longer period, as it is less likely to oxidize into the less usable ferric iron (Fe+3), which can occur in aquatic environments.

Why Iron is Important:

Iron plays an essential role in chlorophyll synthesis, which is responsible for the green pigment in plants. Without sufficient iron, plants may exhibit symptoms of chlorosis, where leaves turn yellow due to a lack of chlorophyll production. This deficiency is particularly visible in new growth, as iron is not highly mobile within plants. In well-planted aquariums, iron supplementation is vital to support lush, vibrant plant growth, especially for iron-demanding species such as Ludwigia and Alternanthera.

Benefits of Seachem Flourish Iron:

• Highly Concentrated: Unlike general-purpose fertilizers, Flourish Iron is concentrated specifically for iron supplementation, ensuring plants receive the optimal amount without unnecessary excess nutrients.
• Ferrous Form: The ferrous iron (Fe+2) provided by this product is more readily absorbed by plant roots and leaves compared to ferric iron (Fe+3), making it an efficient and quick-acting supplement.
• Supports Red Plants: Many species of red plants, such as Rotala rotundifolia and Red Tiger Lotus, thrive with higher iron levels. Regular supplementation with Flourish Iron can help these plants retain their vibrant coloration and overall health.
• Reduces Chlorosis: Flourish Iron helps prevent and reverse chlorosis (yellowing of leaves), a common sign of iron deficiency, especially in newer leaves.

Dosage and Directions:

• Standard Dose: Add 1 capful (5 mL) for every 200 liters of aquarium water. This provides approximately 0.10 mg/L of iron.
• Adjust Dosing: Depending on the plant density and iron requirements of your aquarium, you can adjust the dosage. A heavily planted tank or one with a high proportion of red plants may require more frequent supplementation.
• Regular Monitoring: It's advisable to test iron levels in the aquarium water, especially if you are adding iron through multiple sources (substrates, fertilizers, etc.). This will prevent over-supplementation, which could lead to algae growth or other issues.

How Often to Dose:

• Typically, dosing can be done every 1-2 weeks, depending on the plants’ iron requirements. More frequent dosing may be needed for densely planted tanks or those with red plants.
• If you notice new plant growth turning yellow, especially the younger leaves, this may be a sign that more frequent dosing or higher concentrations of iron are necessary.

Compatibility:

• Safe for Fish and Invertebrates: Flourish Iron is safe for all aquatic inhabitants when used as directed, making it suitable for planted tanks with sensitive species such as shrimp and certain fish.
• Combines Well with Other Seachem Products: Flourish Iron can be used alongside other Seachem plant supplements, such as Seachem Flourish (a comprehensive fertilizer), Seachem Flourish Excel (carbon source), and Seachem Flourish Trace (trace elements), for a complete plant care routine.

Available Sizes:

• Flourish Iron is available in 50 mL, 100 mL, 250 mL, 500 mL, 2 L, and 4 L bottles, ensuring you can scale your supplementation according to the size of your aquarium and plant load.

Storage:

• Store in a cool, dry place, and ensure the bottle is tightly closed after each use to maintain the integrity of the product.

Usage Tips:

• Iron Testing: While not always necessary for casual aquarists, testing iron levels can help maintain optimal levels (typically 0.1 to 0.2 mg/L for planted tanks). There are iron test kits available to ensure your dosing is aligned with plant requirements.
• Spot Dosing: In heavily planted tanks, you can also spot dose by targeting areas with red or iron-demanding plants to maximize efficiency.

Seachem Flourish Iron provides a targeted approach to ensuring your plants receive the iron they need for healthy growth and vibrant coloration, especially in setups that demand extra iron supplementation.
