Seachem Reef Phosphorus

Seachem Reef Phosphorus

Seachem Reef Phosphorus is a concentrated phosphorus supplement for reef aquariums, formulated for reef keepers maintaining corals and macroalgae. It increases phosphorus concentrations without adding dissolved organics, helping support coral and macroalgae growth and coloration while allowing targeted nutrient management.

Key Benefits

• Provides phosphorus, an essential element involved in metabolic processes, protein synthesis and growth.
• Supports the maintenance of phosphorus levels alongside nitrogen levels in reef systems.
• Contains 3,500 mg/L phosphate and 0.117% elemental phosphorus.
• Raises phosphorus concentrations without adding dissolved organics.
• Can be dosed manually or used with an aquavitro® sentia™ dose doser for consistent dosing based on aquarium demand.

Dosage

• Beginner dosage: Use 1/2 cap (2.5 mL) per 160 L (40 US gallons) once a week, or as needed to maintain the desired phosphorus level.
• This dosage raises phosphate by 0.05 mg/L.
• For a specific phosphate increase, use: 0.31vn=m, where v = aquarium volume in litres, n = desired phosphate increase and m = product volume to use in mL.
• Example: To raise phosphate by 0.05 mg/L in 160 litres, dose 0.31 × 160 × 0.05 = 2.5 mL.
