E15 FERACTIV – Iron-Based Fertilizer for Freshwater Aquariums
Iron is a vital micronutrient for aquatic plant metabolism, playing a key role in the formation of chlorophyll and the photosynthesis process. When iron is lacking, plants suffer from iron deficiency chlorosis, which causes leaf yellowing, weakening, and stunted growth. In aquariums, the only absorbable form of iron for plants is ferrous iron (Fe²⁺), but it oxidizes quickly into ferric iron (Fe³⁺), which is no longer available. Tap water contains almost no usable iron, making regular fertilization essential for lush and healthy plant growth.
Dennerle’s E15 FerActiv is a specialized fertilizer designed to deliver highly available ferrous iron in a stabilized, chelated form that remains usable over time. It effectively prevents and corrects iron deficiency symptoms, ensuring healthy green leaves and vigorous plant development. Enriched with potassium and manganese, E15 FerActiv enhances plant strength and promotes consistent, robust growth throughout all life stages.
Thanks to advanced chelating agents, the iron in E15 FerActiv stays protected from rapid oxidation, providing long-lasting benefits. The formula contains no nitrates or phosphates, maintaining aquarium balance and avoiding unwanted algae growth. It’s the ideal solution for aquascapers and hobbyists who want thriving aquatic plants with intense coloration and strong leaf structure.
