SEACHEM - Flourish Phosphorus 250ml - Phosphorus for planted aquarium.

Phosphorus is one of the three major macro–nutrients (nitrogen, phosphorus, potassium) that plants need and is often the limiting factor in the growth of a thriving system. Flourish Phosphorus™ is a safe potassium phosphate solution that takes the guesswork out of phosphate dosing. Unlike competing products that mix nitrate and phosphate in a fixed ratio, Flourish Phosphorus™ (nitrate-free) allows you to dose phosphorus according to your plants' needs without running the risk of an overdose of nitrates. Proper use of Flourish Phosphorus™ will stimulate and accelerate the growth of aquatic plants without promoting algae growth. For maximum effect, use this product in combination with Flourish Nitrogen™ and Flourish Potassium™.

DIRECTIONS: Use 2.5 mL (1/2 capful) per 80 L once or twice a week. This dose raises the phosphorus content by 0.05 mg/L (0.15 mg/L phosphate). The ideal phosphate content varies between systems, but is generally between 0.15–1.0 mg/L. Use MultiTest®: Phosphate to check phosphate levels.
