Provides both ferrous (Fe2+) and ferric (Fe3+) iron sources to maximize benefit to
planted aquaria.
Two-tiered approach to iron supplementation consists of one ingredient to deliver
immediate iron and another ingredient that slowly releases iron during the light cycle,
when the aquarium is illuminated.
Over 50% stronger than most competing products.
Formulated utilizing extensive research on aquatic plant nutrient requirements.
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. This may be demonstrated by observing the increase in plant growth rates that occurs when iron is supplemented in systems in which it was previously immeasurable. Although this increase in plant growth may be desirable, it can be taken too far if iron supplementation exceeds the required concentration; in such an event, it is not uncommon to see increased growth of algae. This is particularly likely to occur in aquaria with excessive concentrations of nitrate and phosphate. As mentioned, iron is also required for the production of chlorophyll, which in turn is required for photosynthesis to occur. A deficiency of iron is physically apparent to the hobbyist 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).
