Brightwell Aquatics Potassion is a powerful ionic potassium supplement designed to restore and maintain ideal potassium levels in reef aquariums. Potassium plays a dual role: it helps corals grow by supporting the formation of aragonite, and enhances their color by contributing to pigment production. This is especially true for small-polyp stony corals (SPS), where vivid blue hues are often linked to proper potassium levels. In ultra-low-nutrient systems or tanks using zeolite filtration, potassium can become depleted over time, which may reduce coral vibrancy and growth. Potassion contains 80,000 ppm of high-purity ionic potassium—more concentrated than most other products—making it an economical and effective choice. When used correctly, Potassion helps reef keepers maintain a potassium range of 390–410 ppm, which is ideal for coral health and appearance. Every batch is formulated using purified water and top-grade materials, making Potassion a trusted supplement for serious reef aquarists looking to support both beauty and balance in their systems.

  • ENHANCES CORAL COLORATION: Supports vivid blue and purple tones in SPS corals by supplying ionic potassium for pigment development.
  • PROMOTES HEALTHY SKELETAL GROWTH: Essential for aragonite formation in reef-building organisms like corals, clams, and tube worms.
  • RESTORES POTASSIUM LEVELS QUICKLY: Highly concentrated formula—80,000 ppm—for faster correction of potassium depletion in ULNS and zeolite systems.
  • PURE AND PHOSPHATE-FREE FORMULA: Made without phosphate, silicate, or unwanted organics. Backed by marine science and reef chemistry research.
  • AMERICAN-MADE EXCELLENCE – Brightwell Aquatics is an industry-leading brand committed to providing innovative and scientifically backed aquatic care products. Made in the USA, we consistently deliver advanced superior quality solutions to elevate the vibrancy and health of your aquarium.
