Seachem Flourish Nitrogen
Provides nitrogen in both the nitrate form & the plant-preferred ammonium form. However, no free ammonia is released.
Flourish Nitrogen is a concentrated (15,000mg/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: 250 ml & 500 ml
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 160L (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 1mg/L nitrate would. This dose is sufficient to provide approximately 4 g of growth (dry) or about 20g (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 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.
