GREEN BRIGHTY IRON is a liquid fertilizer for supplying iron to a planted aquarium. Vigorously growing aquatic plants require iron, and if iron were insufficient, the growth and pigment synthesis of aquatic plants is affected. Daily application of GREEN BRIGHTY IRON to the aquarium eliminates these problems caused by iron deficiency and promotes growth of aquatic plants.
