Seachem Flourish Phosphorus 4 litres

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 PhosphorusTM is a safe solution (4500 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 PhosphorusTM (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 PhosphorusTM will enhance and accelerate the growth of aquatic plants without enhancing algae growth. For maximum benefit use with Flourish NitrogenTM and Flourish PotassiumTM

DIRECTIONS:

Use 2.5 mL (half a cap) for each 80 L (20 gallons*) once or twice a week or as needed in response to signs of phosphorus deficiency (e.g. stunted growth, plant dark green).
