GREEN BRIGHTY NITROGEN is a liquid fertilizer for supplying nitrogen to a planted aquarium. Nitrogen is an essential nutrient for plant growth and insufficient nitrogen can cause poor growth of aquatic plants. Daily application of GREEN BRIGHTY NITROGEN helps enhance leaf colors and promotes plant growth.
*Although the color of the liquid might slightly change due to a loss of the pigment as time advances, it can be used as it is because the principal ingredients do NOT change.
