Seachem Flourish Nitrogen 500ml – Nitrogen Supplement for Planted Aquariums

Seachem Flourish Nitrogen 500ml is a concentrated nitrogen supplement designed for planted aquariums. With a robust 15000 mg/L nitrogen blend, it provides nitrogen in both nitrate and ammonium forms to support plant growth while keeping safety in mind. The ammonium is complexed and unavailable until plants require it, and no free ammonia is released from the bottle. Nitrate is readily usable by many aquarium plants, offering flexibility for different plant species and growth stages.

For best results, pair Flourish Nitrogen with Flourish Phosphorus and Flourish Potassium as part of a complete planted tank nutrition plan. This coordinated approach helps maintain a balanced nutrient profile, which can contribute to healthier growth under appropriate lighting and water conditions. Flourish Nitrogen is formulated to be safe for invertebrates such as shrimp, making it a versatile option for mixed communities.

In practical terms, hobbyists often monitor nitrate levels as part of routine testing and observe plant growth responses when introducing Flourish Nitrogen alongside other nutrients. The product’s concentration allows dosing to fit tank size, plant load, and lighting conditions, enabling experimentation within a responsible care plan. Note that Flourish Nitrogen complements proper lighting, substrate, and carbon sources as part of a holistic plant care routine rather than serving as a stand-alone solution.
