Product details
Seachem Flourish Iron 250mL (476) is a highly concentrated iron supplement designed for planted aquariums. In water, iron is an essential nutrient for chlorophyll production, and deficiency typically shows up first on new or young leaves as yellowing (chlorosis). This product provides iron in the ferrous (Fe2+) form so plants can access it more readily for growth.
Features:
- Helps prevent or correct iron deficiency in planted aquariums, where symptoms commonly start on younger leaves as chlorosis
- Supplies iron as ferrous gluconate, with iron already in the ferrous (+2) form
- Ferrous iron is soluble in water at any pH (supporting practical availability in typical aquarium conditions)
- Aids plant uptake by avoiding strong chelation bonds associated with iron-EDTA approaches
- Ferrous gluconate is described as better suited to foliar feeding than iron-EDTA
- Uses a “complex” approach rather than an iron-EDTA chelate, supporting easier iron availability over time
