Seachem Flourish Phosphorus

Phosphorus is a critical macronutrient for aquatic plants, driving healthy growth, strong root systems, and vibrant foliage. Seachem Flourish Phosphorus provides a safe, controlled source of phosphate that promotes lush plant development without the risk of harmful algae blooms often associated with excess phosphates.

Unlike fish waste or overfeeding—which can lead to inconsistent and excessive phosphate levels—Flourish Phosphorus gives you precise control over nutrient dosing. Ideal for tanks with low fish load or aggressive plant growth, this supplement helps maintain proper NPK balance when used as part of a complete fertilisation program.

  • Provides a concentrated, bioavailable source of phosphorus
  • Promotes strong plant growth and robust root systems
  • Safe for fish, shrimp, and all aquarium inhabitants
  • Perfect for lean dosing or custom nutrient regimens

How to use

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

Directions: Dose according to your aquarium’s phosphate needs. Monitor water parameters regularly to maintain nutrient balance.
