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 flourishing system. Flourish Phosphorusâ¢ is a safe solution (4,500 mg/L phosphate) of potassium phosphate that takes the guess work out of phosphate dosing. Unlike competing products that mix nitrate and phosphate in a fixed ratio, Flourish Phosphorusâ¢ (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 Phosphorusâ¢will enhance and accelerate the growth of aquatic plants without enhancing algae growth. For maximum benefit, use withÂ Flourish Nitrogenâ¢Â andÂ Flourish Potassiumâ¢. Flourish Phosphorusâ¢ is safe for invertebrates such as shrimp.
