Seachem Flourish Phosphorus

Phosphorus is a crucial macro nutrient for plant growth, often becoming the limiting factor in aquatic systems. Flourish Phosphorus™ offers a reliable solution for this need, providing a safe concentration of 4,500 mg/L phosphate in the form of potassium phosphate. This product eliminates the guesswork associated with phosphate dosing. Unlike some products that combine nitrate and phosphate in a fixed ratio, Flourish Phosphorus™ is nitrate-free, allowing precise phosphorus dosing tailored to your plants' requirements without the risk of excessive nitrate levels. When used as directed, Flourish Phosphorus™ effectively promotes the growth of aquatic plants while minimizing the risk of algae proliferation. For optimal results, it is best used in conjunction with Flourish Nitrogen™ and Flourish Potassium™. Additionally, Flourish Phosphorus™ is safe for invertebrates such as shrimp.
