• Highly-concentrated and stable iron solution for supplementing aquaria containing hermatypic organisms (i.e. “photosynthetic” or zooxanthellate corals, clams, and their allies), macroalgae, coralline algae, mangroves, marsh grasses, and other desirable marine algae and plants.
• Particularly suited to systems outfitted with a refugium or mud system.
• Stronger than most competing products.
• Composed of purified water and ultra-high purity materials.
• Formulated by a marine scientist.
• Available in 250 ml, 500 ml, and 2 L sizes.

Photosynthesis is carried out within cell bodies known as Chloroplasts. Iron is utilized in the electron transport chain within the chloroplasts, and is therefore required by photosynthetic organisms for continued functioning and health. In marine aquaria, these organisms include macroalgae, marsh grasses and mangroves, encrusting calcareous algae, and the symbiotic zooxanthellae and zoochlorellae that reside within the tissues of hermatypic corals, clams, and their allies, as well as in some sponges. In effect, the availability of iron becomes a limiting factor in the rate of photosynthesis, and hence the rate of nutrient uptake for growth, for these organisms.
