Seachem Flourish Iron

Seachem Flourish Iron 250mL provides a highly concentrated source of ferrous iron (Fe²⁺), the form of iron most readily absorbed by aquatic plants. Iron is critical for chlorophyll production, vibrant red coloration, and strong new growth.

In high-light or CO₂-injected aquariums, iron is quickly consumed — and without supplementation, red plants lose intensity and new growth becomes weak or yellow.

What It Helps Fix

✔ Pale or washed-out red plants
✔ Yellowing new leaves (chlorosis)
✔ Weak new growth
✔ Poor colour intensity
✔ Slowed top growth in stem plants

Iron deficiency often shows in new leaves first, with veins remaining green while surrounding tissue yellows.

How You Know You Need It

• Red plants lack vibrancy

• You run high light or injected CO₂

• You dose macros but not additional iron

• New growth appears pale or weak

• Your aquascape lacks colour intensity

Iron is especially important for species like Rotala, Ludwigia, and other red stem plants.

Dosage

Standard Dose: 5mL per 200L, 1–2 times per week
For high-demand planted tanks, dosage may be adjusted based on plant response and iron testing.

Best used alongside a comprehensive fertiliser program such as Seachem Flourish and balanced macro nutrients.

For deeper reds, healthier new growth, and vibrant aquascapes, Seachem Flourish Iron 250mL is an essential targeted supplement.
