Seachem Flourish Nitrogen (Options Available)

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.
