Supplies nitrogen, one of the three main macronutrients required by plants, in both the nitrate form and the plant-preferred ammonium form. Does not release ammonia. 500 ml treats up to 10,000 gallons.

Recommended Dosage:
Beginner: Use 2.5 mL (half a cap) for each 160 L (40 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.

Expert: The beginner dose raises nitrogen by the same degree that 1 mg/L nitrate would. This dose is sufficient to provide approximately 4 g of growth (dry) or about 20 g (hydrated) over a 1 month period (assuming all other necessary nutrients are provided). For increased growth, use proportionately more. To target a specific nitrogen increase, dose according to the following formula: 0.25vn=m, where v= volume of tank in gallons*, n=desired nitrogen increase (if using a "nitrate equivalent" value for "n" then use a factor of 0.05 instead of 0.25 in the formula) and m=volume of product to use in mL. For example, to raise 20 gallons* by 0.20 mg/L nitrogen, you would use: 0.25*20*0.20=1 mL.

Because one-half of the nitrogen in Flourish Nitrogen™ is from nitrate you can get a reasonable estimate of nitrogen levels by doubling a nitrate reading.

*1.5% Soluble Nitrogen
Derived from: potassium nitrate, urea (iminium salt).

General Information
Nitrogen is one of the main three macro nutrients (nitrogen, phosphorus, potassium: NPK) required by plants and can often become the limiting factor to growth in a ?ourishing system. Flourish Nitrogen is a concentrated (15,000 mg/L) blend of nitrogen sources. It provides nitrogen in both the nitrate form and the plant-preferred ammonium form. However, no free ammonia is released because the ammonium in Flourish Nitrogen is complexed and unavailable until utilized by the plants. Flourish Nitrogen also provides nitrate for those plants that can readily utilize nitrate as well. For maximum benefit, use with Flourish Phosphorus and Flourish Potassium. Flourish Nitrogen is safe for invertebrates such as shrimp.

About Seachem
Seachem's philosophy is that the knowledgeable hobbyist makes the best customer. This is reflected in solid and reliable customer education and support as well as products proven in science and performance. While Seachem has grown rapidly into a national and international firm, it retains the culture of a small company and is readily available to its customers.

For over three decades, Seachem has been a company rooted in sound science. Their experience in the hobby and an educated staff of chemists and biologists are part of the package when you purchase Seachem products. Seachem remains as one of the few surviving independent and privately owned pet care companies. Seachem is owned and operated by hobbyists. All of their employees are hobbyists who maintain aquariums at home and at the office. Seachem itself was started because one such hobbyist found the available solutions to aquarists' problems wanting. This resulted in Seachem's very first product: Cupraplex™ (today known as Cupramine™). Over thirty years later Seachem is still approaching old problems in a new way.
