Flourish Nitrogen is a concentrated blend (15,000 mg/L) of nitrogen sources. It provides nitrogen in both nitrate form and the plant-preferred form, ammonium.

Key Features:

• Nitrogen supplement for planted aquariums
• A blend of nitrogen sources at a concentration of 15,000 mg/L
• Provides nitrogen in both nitrate and ammonium forms

Instructions:
Beginners
Use 2.5 ml (half cap) for every 160 liters (40 US gallons) twice a week or as needed in response to signs of nitrogen deficiency (e.g., stunted growth, yellowing). For smaller doses, please note that each cap thread is approximately equivalent to 1 ml.

Experts
The starter dose raises the nitrogen level by the same degree that 1 mg/L nitrate would rise. This dose is sufficient to provide about 4 grams of growth (dry) or about 20 grams (hydrated) over one Month (assuming all other necessary nutrients are provided). To increase growth, use a larger ratio.

To achieve a specific increase in nitrogen level, dose according to the following formula: 0.25vn=m, where v=volume of the tank in gallons, n=desired increase in nitrogen (if using "nitrate equivalent" value for "n" use a factor of 0.05 instead of 0.25 in the formula) and m=volume of the product to be used in ml. For example, to raise 20 gallons by 0.20 mg/L of nitrogen, you would use: 0.25*20*0.20=1 ml.
