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.

Very cool and comfortable pillows. Great value.
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
These pillows are everything described on the site. They do retain shape and don’t flatten out after sleeping all night. They are nice and clean looking and comfortable. The fit on my king size bed is perfect cause I prefer the size to king size. Haven’t had to wash them yet but I have had other pillows with the same material inside and the wash ability is great.

Great pillow
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
The pillows feel great. Being able to remove portions of the interior allowed me and my wife to have a perfect fit. They do stay cool which seems to have helped with my restlessness.

It works! Quality pillow.
Size: Standard (1 Count), Color: Original White (Cooling)
This does actually provide a cooling effect, and it's very comfortable! The accompanying literature is helpful too. I believe this to be a quality pillow for the price.

Most comfortable pillow I’ve ever slept on
Size: Queen (1 Count), Color: Crescent White(cooling)
This is the most comfortable pillow I have ever slept on. It doesn't mash down like other pillows. Cradles my neck perfectly plus it’s cool. I broke my neck a couple of years ago and this pillow feels very good and comfortable. Definitely recommend to everyone. Ive used it since May and it’s retained its shape.

Smell
Size: Queen (2 Count), Color: Original White (Cooling)
The fact that there are not more comments on the smell of these pillows has me worried about some of yall. Listen, I LOVE the weight, and the firmness, it’s perfect for that. However, these pillows are RANK. They have a very strong mildew-ish smell that lingers. I took the outer cover off and washed it and let the pillow air out for a few days, the smell is still very strong when you press your face against it, which one does because it is in fact designed for that purpose. It smells so bad. It’s nauseating. I can smell it through two pillowcases and blanket that I threw on top of them hoping an extra layer would trap the smell. I’ll bake them in the Texas sun tomorrow and hope that helps, because otherwise these are the perfect pillows for someone who wants to feel like they are hugging a torso but can’t stand the sound/feel of someone else breathing. I don’t know…4 stars, if the smell goes away I’ll come back. Update: many many days later. Either they don’t really smell anymore or I got use to it. They’ve held their firmness and shape well. I like them.
