Iron is an essential element for plants, both aquatic and terrestrial: it is utilized in the production of chlorophyll and activates some enzymes that take part in metabolic reactions; it does all of this, however, in very small concentrations. Iron is considered a micronutrient, and it is often the limiting element in plant production in some aquatic habitats.

A deficiency of iron is physically apparent as plant leaves which appear yellow or even somewhat transparent. In later stages, the leaves eventually disintegrate under gentle water current or disturbance. While this condition may also be caused by other chemical and environmental factors, it is seemingly most often the result of insufficient available iron (note that K, Mg, and N are also important).

Brightwell Aquatics Florin Fe delivers iron in two steps: immediate and delayed. This is accomplished through natural biological and photochemical reactions taking place within ponds, and results in a more stable iron concentration than is attained with other methods of liquid iron supplementation.
