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.

Product Details:

  • Product Name: Seachem Flourish Nitrogen™

  • Size: 100 ml

  • Type: Concentrated macronutrient supplement (Nitrogen).

  • Use: For all freshwater planted aquariums.

How To Use:

  • Dosage: Use 1 capful (5 mL) for every 500 L (125 US gallons) 2-3 times a week. Note: Dosage requirements can vary significantly based on plant mass, lighting, and fish load.

  • Application: For precision dosing, use a syringe. Disperse evenly into the aquarium. For maximum benefit, add after a water change.

  • 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.

Works if you need help. Not a miracle in a bottle.
Size: 1 Count (Pack of 1)
It has worked every time I've used this product. Won't fix a damage catalytic converter but will help you pass the test if your car almost passed.

Worked like a charm.
Size: 1 Count (Pack of 1)
Used it as directed. Down to an eighth of a tank. Poured it in and added enough gas to get back to one half a tank. Wanted to get it mixed in really well. Immediately jumped on the interstate and ran 75 MPH for 40 miles. Stopped and filled the tank and when I restarted the engine, the light was off. Coincidence? Not a chance. Light had been on continuously for weeks. AutoZone said I needed a catalytic converter. Nope. One thing I found out the hard way. If your gas filler has a flap at the top, make sure it is easy to push aside. Mine had a little release button near the top that the filler hose would depress before the flap would release. Dumped the first bottle right on the ground. Twelve bucks wasted. No one to blame but me, I guess. Still a bargain, even at twice the price.

Size: 1 Count (Pack of 1), Size: 1 Count (Pack of 1)
I read the specs on this product and it was guaranteed to cleanse as well as turn engine light off in vehicle. I received it March 14.2026 and used it on March 15.2026 I took a picture on Sunday before I entered it into the gas tank engine light was on at that time. Today is March 17.2026 and engine light is still on. The truck was driven for one hour on the 15th 45 minutes on the 16th and 50 minutes on 17 March. Still the engine light is on. Got home parked the vehicle took a picture again to show engine light is still on product guaranteed it was shut it off, but unfortunately product does not work.
