Flourish Nitrogen -
The container of Seachem Flourish Nitrogen is a top of the line nitrogen blend supplement designed specifically for use in delicate planted aquariums. Nitrogen is one of the main three main macro nutrients, alongside phosphorus and potassium, that are required by aquatic plants, with their absence becoming a limiting factor to healthy growth and development. This concentrated (15,000 mg/L) blend of nitrogen sources provides essential nitrogen in both the nitrate form as well as the plant-preferred ammonium form.
To make things even safer, absolutely no harmful free ammonia is released because the ammonium in Seachem Flourish Nitrogen is complexed and wholly unavailable for consumption until utilized by the plants themselves. The solution is completely safe for fish and sensitive invertebrates such as shrimp.
Directions:
Beginner
Use 2.5 mL (half a cap) of the solution for each 160 L (40 US gallons) of aquarium water 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 of 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 Nitrogenâ„¢ is from nitrate you can get a reasonable estimate of nitrogen levels by doubling a nitrate reading.
