Seachem Flourish Nitrogen is a concentrated nitrogen supplement specially formulated to provide aquatic plants with a readily available source of nitrogen in freshwater planted aquariums. Nitrogen is an essential macronutrient required for healthy plant growth, playing a critical role in protein synthesis, chlorophyll production, and overall plant vitality. Seachem Flourish Nitrogen delivers nitrogen in multiple forms, including nitrate and ammonium, ensuring aquatic plants have access to the nitrogen they need to thrive. Deficiencies in nitrogen can result in stunted growth, pale or yellowing leaves, and overall poor plant health. Safe for fish and invertebrates when used as directed, Seachem Flourish Nitrogen is easy to dose and pairs seamlessly with other Seachem Flourish fertiliser products to support a complete and balanced planted aquarium fertilisation routine. Regular use promotes lush, healthy, and vigorous aquatic plant growth, enhancing the overall beauty and vitality of any freshwater planted aquarium or aquascape.
