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™.
Sizes: 100 mL, 250 mL, 500 mL, 2 L, 4 L, 20 L
Unlike competing products, Flourish Nitrogen™ is entirely phosphorus-free, making it possible to adjust the nitrogen level in an aquarium without affecting phosphorus levels.
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:
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, or, you can use Seachem’s MultiTest: Total Nitrogen™ (coming soon!) to accurately measure total nitrogen while distinguishing between nitrate, ammonia and organic nitrogen.
