Description
Fuel Lush, Rapid Plant Growth & Combat Yellowing Leaves
Give your aquatic plants the fundamental building block they need to thrive. Seachem Flourish Nitrogen™ is a concentrated blend of nitrogen compounds designed to prevent deficiency, which is a primary cause of slow growth, pale leaves, and poor plant health. Ensure your planted aquarium has a sufficient supply of this essential macronutrient for vibrant, dense, and healthy growth.
Key Features & Benefits:
-
Targets Nitrogen Deficiency: Directly addresses the cause of stunted growth and yellowing (chlorosis) in older leaves.
-
Promotes Vigorous Growth: Nitrogen is a key component of chlorophyll and amino acids, fueling lush, green, and rapid plant development.
-
Comprehensive Formula: Contains both nitrate and non-nitrate nitrogen sources to suit various plant uptake preferences and tank conditions.
-
Ideal for Heavily Planted Tanks: A must-have supplement for high-growth, high-light, and CO2-injected aquariums where nitrogen is consumed rapidly.
-
Safe for All Aquaria: Perfectly safe for fish, invertebrates, and beneficial bacteria when used as directed.

Important: Always test your nitrate (NO3) levels regularly. Aim for a range of 5-20 ppm. Adjust your dosage of Flourish Nitrogen™ to maintain this range, especially if you have a low fish bioload.
Who is this product for?
Seachem Flourish Nitrogen™ is essential for:
-
Aquarists with heavily planted tanks that consume nitrogen faster than fish waste can produce it.
-
Keepers of "Low-Waste" tanks (e.g., tanks with few fish or shrimp-only tanks).
-
Anyone noticing pale or yellowing leaves, particularly on older growth.
-
Hobbyists using high-light and CO2 systems who need to balance their macronutrients (NPK).
The Seachem Flourish® Range:
Flourish Nitrogen™ is one part of a complete nutrient system. For optimal results, combine with:
-
Flourish Phosphorus™ & Flourish Potassium™: To balance all major macronutrients (NPK) and prevent lockout.
-
Flourish®: Provides a comprehensive base of essential micronutrients and trace elements.
-
Flourish Excel®: A source of bioavailable organic carbon.
Order with Confidence:
This 100ml bottle is an excellent size for small to medium aquariums or for targeted supplementation. For larger tanks, please see our larger, more economical size options.
FAQ Section (Suggested for the product page):
Q: How do I know if my plants need nitrogen?
A: The classic sign of nitrogen deficiency is the yellowing (chlorosis) or fading of older, established leaves, while new growth may appear stunted or pale green.
Q: Will this increase my nitrate levels and cause algae?
A: Used correctly, it prevents nitrogen deficiency, which itself can cause algae. Algae blooms are typically caused by imbalances (e.g., high nitrogen but low CO2 or phosphorus). The key is consistent, measured dosing based on tank consumption and regular testing.
Q: Is this a replacement for a comprehensive fertilizer?
A: No. Flourish Nitrogen™ is a supplemental source of one specific macronutrient. Plants also require phosphorus, potassium, and a full range of micronutrients (found in Seachem Flourish®). This product is for tailoring your regimen to your tank's specific needs.
