Seachem Flourish Phosphorus

Seachem Flourish Phosphorus is a phosphorus supplement for planted aquariums that enhances and accelerates the growth of aquatic plants while being safe for invertebrates and allowing for precise dosing without the risk of overdosing nitrates.

  • Phosphorus supplement for the planted aquarium
  • A safe 4500 mg/L solution of potassium phosphate
  • Takes the guesswork out of phosphate dosing

Seachem Phosphorus 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 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.

Directions

BEGINNER: Use 2.5 mL (half a cap) for each 80 L (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).

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 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.
