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
