The 250 ml 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.
