Seachem Flourish Phosphorus 500 ml.Phosphorus supplement for the planted aquariumA safe 4500 mg/L solution of potassium phosphateTakes the guesswork out of phosphate dosingPhosphorus is one of the main three macronutrients (nitrogen, phosphorous, potassium: NPK) required by plants and can often become the limiting factor to growth in a flourishing system. Flourish Phosphorus is a safe solution (4,500 mg/L phosphate) of potassium phosphate that takes the guesswork out of phosphate dosing. Unlike competing, products that mix nitrate and phosphate in a fixed ratio, Flourish Phosphorus (being nitrate free) allows you to dose phosphorus according to the needs of your plants without the risk of overdosing nitrates. When used as directed, Flourish Phosphoruswill enhance and accelerate the growth of aquatic plants without enhancing algae growth. For maximum benefit, use Flourish NitrogenandFlourish Potassium. Flourish Phosphorus is safe for invertebrates such as shrimp.Directions:BeginnerUse 2.5 mL (half a cap) for each 80L (20 US gallons) once or twice a week or as needed in response to signs of phosphorus deficiency (e.g. stunted growth, plant dark green).ExpertThe beginner dose raises phosphorus by 0.05 mg/L (0.15 mg/L phosphate). The ideal phosphate level will vary but generally ranges from 0.151.0 mg/L. Use MultiTest Phosphate to monitor phosphate levels. To target a specific phosphate increase, dose according to the following formula: 0.8vp=m, where v= volume of the tank in gallons, p=desired phosphate increase, and m=volume of product to use in mL. For example to raise 20 gallons to 0.1 mg/L phosphate you would use: 0.8*20*0.1=1.6 mL.
