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. Ammonium becomes available after conversion of urea (carbamide). 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.

A: Ammonium and ammonia are not the same thing. No free ammonia is released because the ammonium in Flourish Nitrogen™ is complexed and unavailable until utilized by the plants.
A: In studies we have done isolating the effects of the ammonium form and nitrate form of nitrogen on plant growth, we have found that most plants prefer to utilize nitrogen in the ammonia (ammonium NH4+) form. Note, however, that certain plants derive a greater benefit from the nitrate form (NO3). That's why Flourish Nitrogen™ contains both the nitrate form as well as in an ammoniacal equivalent form.
A: This is true, but only when nitrogen levels become excessive, that is, when there is more nitrogen available than the plants can use. When this happens, it becomes available to algae. Nitrogen is still vital to plant growth, though. Flourish Nitrogen™ should be used in cases where there is a nitrogen deficiency.
