Seachem Flourish Phosphorus is a safe, concentrated (4,500 mg/L) solution of potassium phosphates designed to address phosphorus deficiency in the planted aquarium. Phosphorus is one of the three primary macro-nutrients (NPK) required by plants and is a key component of ATP, the energy molecule for all living cells. Flourish Phosphorus allows for the precise addition of phosphates without the risk of over-dosing nitrates, making it an essential tool for "dialing in" the specific nutrient needs of high-tech aquascapes.
Flourish Phosphorus is engineered to provide total control over your water column chemistry, ensuring plants never "stall" due to nutrient limitation.
Nitrogen-Free Formula: Unlike many terrestrial fertilizers, this supplement provides pure phosphorus, allowing you to manage your nitrate and phosphate levels independently.
Prevents Growth Stunting: Eliminates the common signs of phosphorus deficiency, such as dark green or purple foliage and significantly slowed growth rates.
Encourages Lush Foliage: Provides the essential energy building blocks for rapid stem elongation and leaf development in demanding aquatic species.
Algae Control Strategy: Maintaining a steady, low level of phosphate (rather than zero) helps plants outcompete opportunistic algae like Green Spot Algae (GSA).
Safe for Livestock: Completely non-toxic and safe for all freshwater fish, as well as sensitive ornamental shrimp and snails.
How much Seachem Flourish Phosphorus should I use?
The standard dose is 2.5 mL (half a capful) per 80 L (20 US gallons) once or twice a week. This dose raises phosphate by 0.05 mg/L.
What is the ideal phosphate level for a planted tank?
Most aquascapers aim for a stable phosphate level between 0.1 and 1.0 mg/L, depending on light intensity and CO2 levels.
Will adding phosphorus cause hair algae?
No. Algae is typically caused by an imbalance of nutrients or ammonia. In fact, Green Spot Algae is often a direct sign that your phosphate levels are too low for your plants to thrive.
Seachem Flourish Nitrogen: The essential partner to Flourish Phosphorus for maintaining the ideal NPK balance.
