    Iron in the Marine Aquarium
    Iron is crucial for photosynthesis in all plants, including caulerpa, mangroves, calcareous algae, and symbiotic algae in coral, marine clam and other invertebrate tissues. In marine aquariums, iron is used up rapidly and removed through precipitation. Reef Basis Iron is chelated with EDTA, a professional sequestrant that will allow it to remain soluble until used by the life that requires it. Growth of all photosynthetic organisms also require strong lighting of proper spectrum. Consult your lighting supplier for assistance in the proper type of light, and photo periods for the corals and algae that you are growing.

    Keep out of reach of children. Not for human consumption. Contains Iron EDTA, If ingested drink water, contact a poison control center. If in eyes flush with water.
