Brightwell Aquatics Potassion High-Strength Ionic Potassium Supplement for Reef Aquariums Supports Coral Growth & Color Enhances SPS LPS Invertebrate Health, 2L

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.
