This safe solution of potassium phosphate will enhance and accelerate the growth of aquatic plants without enhancing algae. Takes the guess work out of phosphate dosing. 250 ml treats up to 5,000 gallons.

Recommended Dosage:
Beginner: Use 2.5 mL (half a cap) for each 80 L (20 gallons*) once or twice a week or as needed in response to signs of phosphorus deficiency (e.g., stunted growth, plant dark green).

Expert: The beginner dose raises phosphorus by 0.05 mg/L (0.15 mg/L phosphate). The ideal phosphate level will vary, but generally ranges from 0.15-1.0 mg/L. Use Seachem's MultiTest: Phosphate test kit (#901377) to monitor phosphate levels. To target a specific phosphate increase, dose according to the following formula: 0.8vp=m, where v= volume of 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.

Derived from: Potassium Phosphate.

General Information
Phosphorus is one of the main three macro nutrients (nitrogen, phosphorous, potassium: NPK) required by plants and can often become the limiting factor to growth in a ?ourishing 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 Phosphorus will enhance and accelerate the growth of aquatic plants without enhancing algae growth. For maximum benefit, use with Flourish Nitrogen and Flourish Potassium. Flourish Phosphorus is safe for invertebrates such as shrimp.

About Seachem
Seachem's philosophy is that the knowledgeable hobbyist makes the best customer. This is reflected in solid and reliable customer education and support as well as products proven in science and performance. While Seachem has grown rapidly into a national and international firm, it retains the culture of a small company and is readily available to its customers.

For over three decades, Seachem has been a company rooted in sound science. Their experience in the hobby and an educated staff of chemists and biologists are part of the package when you purchase Seachem products. Seachem remains as one of the few surviving independent and privately owned pet care companies. Seachem is owned and operated by hobbyists. All of their employees are hobbyists who maintain aquariums at home and at the office. Seachem itself was started because one such hobbyist found the available solutions to aquarists' problems wanting. This resulted in Seachem's very first product: Cupraplex™ (today known as Cupramine™). Over thirty years later Seachem is still approaching old problems in a new way.
