Flourish Nitrogen is a concentrated blend (15,000 mg/L) of nitrogen sources. It provides nitrogen in two forms, nitrate form and the preferred ammonium form for plants.

Main Features:

• Nitrogen supplement for planted aquariums
• Blend of nitrogen sources with a concentration of 15,000 mg/L
• Provides nitrogen in nitrate form and ammonium form

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

For Advanced Users
The beginner dose raises the nitrogen level by the same degree as 1 mg/L nitrate. 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 available). To increase growth, use a proportionally larger amount.

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