Seachem Flourish Phosphorus – Targeted Phosphate Supplementation

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.

Precise Macro-Nutrient Management & Algae Prevention

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.

    FAQ Section: Common Questions

    • 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.
