Seachem Reef Potassium™ is a highly concentrated (100,000 mg/L) potassium supplement specifically formulated for the reef aquarium. Potassium is a vital element required for protein synthesis, metabolic processes, and the overall growth of corals and macroalgae. In many reef systems, particularly those using nitrogen and phosphorus supplementation, potassium utilization rates increase significantly. Supplementing with Reef Potassium™ provides a targeted way to maintain optimal levels (380–400 mg/L) to enhance coral vitality and intensify red and pink coloration.
Reef Potassium™ is engineered to provide a clean, effective source of potassium without the risk of adding unwanted organics or phosphates.
Intensifies Coral Color: Specifically noted for bringing out deep red and pink pigments in various stony coral species.
Metabolic Essential: Supports critical biological functions, including protein synthesis and skeletal development.
Pure Formula: Provides a targeted means of increasing potassium concentrations without adding dissolved organics or affecting phosphate levels.
Doser Ready: Ideally suited for use with automated dosing systems like the aquavitro® sentia™ for consistent, stable concentrations.
Concentrated Efficiency: At 10% elemental potassium, this formula is highly efficient, requiring smaller doses to reach target levels compared to less concentrated brands.
How much Seachem Reef Potassium™ should I dose?
Beginner: Use 5 mL (1 capful) per 160 L (40 US gallons) twice a week.
Advanced: This dose raises potassium by 3 mg/L. (where volume in liters, desired increase, and mL of product) to target specific levels.
What is the ideal potassium level for a reef tank?
While it varies by system, the generally recommended range is 380–400 mg/L, mirroring natural seawater levels.
Does it contain other minerals?
No. Reef Potassium™ is a dedicated supplement derived from potassium chloride, intended to allow hobbyists to manage potassium independently of other trace elements.
Seachem Reef Nitrogen™ & Reef Phosphorus™: Use these to maintain the nutrient balance that often drives the need for extra potassium.
Seachem Reef Plus™: A full-spectrum supplement providing the vitamins and amino acids that work alongside potassium for total coral health.
Seachem Reef Advantage Magnesium™: Essential for maintaining t he ionic balance that keeps your primary elements in solution.
