Seachem Flourish Nitrogen

Nitrogen is one of the three main macronutrients (Nitrogen, Phosphorus, Potassium: NPK) required by plants and can often become the limiting factor for growth in a thriving system. Flourish Nitrogen™ is a concentrated blend (15,000 mg/L) 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 used by plants. Ammonium becomes available after conversion from urea (carbamide). Flourish Nitrogen™ also provides nitrate for plants that can easily use nitrate as well. For maximum benefit, use with Flourish Phosphorus™ and Flourish Potassium™. Flourish Nitrogen™ is safe for invertebrates such as shrimp.
