Seachem Flourish Nitrogen

Nitrogen is one of the primary macronutrients plants need for vigorous growth, lush foliage, and vibrant colour. Seachem Flourish Nitrogen provides a safe, concentrated source of both nitrate and ammonium forms of nitrogen, giving plants immediate access to this vital nutrient without compromising water quality.

In many aquariums, nitrogen levels can be too low due to light fish stocking or heavy plant growth, leading to stunted growth and yellowing leaves. Flourish Nitrogen corrects these deficiencies, ensuring plants maintain strong stems, healthy leaves, and rapid development.

• Delivers a balanced, bioavailable nitrogen source
• Prevents yellowing leaves and stunted growth
• Safe for fish, shrimp, and invertebrates
• Perfect for custom fertilisation routines or lean dosing

How to use

Use 2.5 mL (half a cap) for each 160 L (40 US gallons) twice a week or as needed in response to signs of nitrogen deficiency (e.g. stunted growth, chlorosis). For smaller doses, please note that each cap thread is approximately 1 mL.

Directions: Dose according to plant load and desired nitrate levels. Use alongside other Seachem Flourish supplements for complete nutrition.
