<p><b>Seachem Flourish Nitrogen Plant Growth Fish &amp; Aquatic Supplement</b></p><p>For more than 30 years, aquarium hobbyists have turned to Seachem Laboratories for products designed by chemists and biologists. Help aquarium plants thrive with Seachem Flourish Nitrogen. This concentrated (15,000 mg/L) blend of nitrogen sources (nitrate and ammonium) does not release free ammonia. Seachem Flourish Nitrogen is safe for invertebrates like shrimp.</p><p><b>Ingredients: </b>potassium nitrate, urea (iminium salt)</p><p><b>Guaranteed Analysis: </b>Total Nitrogen - 1% Soluble Potash - 2%</p><p><b>Instructions: </b>BEGINNER: Use 2.5 mL (half a cap) for each 160 L (40 US gallons) twice a week or as needed in response to signs of nitrogen deficiency (e.g. stunted growth, chlorosis). For smaller doses, please note that each cap thread is approximately 1 mL. EXPERT: The beginner dose raises nitrogen by the same degree that 1 mg/L nitrate would. This dose is suf?cient to provide approximately 4 g of growth (dry) or about 20 g (hydrated) over a 1 month period (assuming all other necessary nutrients are provided). For increased growth use proportionately more. To target a speci?c nitrogen increase, dose according to the following formula: 0.25vn=m, where v= volume of tank in gallons, n=desired nitrogen increase (if using a ?nitrate equivalent? value for ?n? then use a factor of 0.05 instead of 0.25 in the formula) and m=volume of product to use in mL. For example to raise 20 gallons by 0.20 mg/L nitrogen you would use: 0.25*20*0.20=1 mL. Because one-half of the nitrogen in Flourish Nitrogen? is from nitrate you can get a reasonable estimate of nitrogen levels by doubling a nitrate reading.</p>
