Seachem Flourish Nitrogen is an essential plant supplement designed to safely and effectively increase nitrate (NO3) levels in the planted aquarium. Nitrogen is a key component of chlorophyll (for photosynthesis) and amino acids (for building proteins), making it vital for all plant health and growth. A lack of nitrogen is a common deficiency in densely planted tanks, often leading to symptoms such as yellowing of older leaves, slow growth, and general plant fading. Flourish Nitrogen supplies nitrogen in two bio-available forms: nitrate and the ammonium form. However, the ammonium is held in a complex and is not released until plants utilize it, making the product safe for fish and reducing the risk of ammonia spikes. Key Benefits and Features: Essential Macronutrient: Supplies vital nitrogen, necessary for all plant functions and structures. Dual Source: Provides nitrogen in both nitrate and a complexed, safe ammonium form. Deficiency Prevention: Corrects symptoms of nitrogen deficiency, such as yellowing (chlorosis) and stunted growth. Safe Formula: The ammonium content is complexed for safety, preventing free ammonia build-up that is harmful to fish. Easy Dosing: Simple to dose to achieve target nitrate concentrations. Dosing Recommendation: Standard Dose: Use 2.5 ml (half a capful) for every 160 litres of water. Result: This dose raises nitrogen by 0.8 mg/L (ppm), or 3.6 mg/L equivalent of nitrate. Recommended Frequency: Dose 1–2 times per week or as needed to maintain the desired nitrogen level, typically in the range of 10 to 20 mg/L nitrate. Use a reliable nitrate test kit to monitor levels before and after dosing.
