Seachem Flourish Phosphorus | 250ml

Seachem Flourish Phosphorus is one of the three main 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.

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.
