Flourish IRON 500ml Seachem

Flourish Iron Seachem – Iron Supplement for Planted Aquarium

Flourish Iron is an iron supplement specifically designed for planted aquariums. Iron is an immobile element in plants, meaning it cannot be redistributed from old leaves to new ones. Deficiencies therefore appear primarily on young leaves.

Main Features

Benefits and Functioning

Iron plays an essential role in the production of chlorophyll. A deficiency leads to chlorosis, characterized by yellowing of young leaves and reduced stem development. In prolonged cases, each new leaf becomes progressively lighter than the previous one.

Iron exists in two main forms: ferrous and ferric iron. Ferric iron becomes insoluble at a pH above about 5.5 and precipitates, making it unavailable for foliar absorption. To counter this phenomenon, some products use chelated ferric iron, which however limits its real availability to plants.

Flourish Iron uses a ferrous gluconate complex, not a chelate. This means the iron is already in its assimilable form, saving plants the energy needed to convert it. Additionally, the weaker iron-gluconate bond compared to chelated iron promotes more efficient foliar absorption.

Gluconate also provides an additional benefit by serving as a complementary carbon source for plants.

Usage Tips

Regularly dose according to the needs of the plants and the potential appearance of deficiency symptoms. Adjust the dosage to maintain an intense green coloration and balanced growth.
