Nitrogen supplement for the planted aquarium
15000 mg/L blend of nitrogen sources
Provides nitrogen in both the nitrate form and the ammonium form
No free ammonia is released
Safe for invertebrates such as shrimp

 
 Seachem Flourish Nitrogen for Planted Aquarium has nitrogen which 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 (15000 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.
