SEACHEM FLOURISH IRON 100ml – High-Concentration Ferrous Iron Supplement (Fe²⁺) for Planted Freshwater Aquariums
Seachem Flourish Iron 100ml is a high-potency liquid iron supplement formulated with ferrous gluconate (Fe²⁺) to support healthy and vibrant aquatic plant growth. Ideal for heavily planted or high-demand tanks, this product addresses iron deficiencies that can lead to chlorosis (yellowing of leaves), poor growth, and color loss—especially in red plants like Rotala, Ludwigia, and Alternanthera.
Unlike typical EDTA-bound iron supplements (Fe³⁺), Flourish Iron delivers iron in the ferrous form (Fe²⁺), which is more easily absorbed by plants without requiring energy-consuming reduction. It promotes chlorophyll production, enhances photosynthesis, and intensifies leaf pigmentation without contributing phosphates or nitrates—making it safe for fish and invertebrates, and preventing unwanted algae.
Flourish Iron is fully compatible with Seachem’s full range of plant care products, including Flourish™, Flourish Excel™, Flourish Trace™, and more, making it a versatile and essential tool for complete fertilization.
