Flourish Nitrogen


  •  Nitrogen supplement for the planted aquarium
  •  15,000 mg/L blend of nitrogen sources
  •  Provides nitrogen in both the nitrate form and the ammonium form.



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 flourishing 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.




BEGINNER: Use 2.5 mL (half a cap) for each 160 L (40 US  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.
