Description
Our Coral Essentials, Coral Power Potassium is a concentrated solution of Potassium Chloride, 100,000ppm for marine aquariums. It is essential for healthy growth of both soft and hard coral, enhanced red and pink colouration in corals, as well as promoting coral exoskeleton growth. Potassium is one of the fundamental elements for marine tanks. Potassium is an important major ion that supports cellular function, coral health/pigmentation, and macroalgae growth. Potassium is used in both coral skeleton formation and cellular processes. It is also used by zooxanthellae as it is directly involved in the biosynthesis of glucose through photosynthesis. Additional benefits of dosing potassium (K) in a marine aquarium:
- Maintains ionic balance and osmotic health – potassium is a major intracellular cation for animals and algae; maintaining natural seawater levels supports normal cell function, nerve/muscle activity, and osmoregulation in fish and invertebrates.
- Supports coral physiology and coloration – adequate potassium is linked to healthy coral metabolism and pigmentation in some species (especially soft corals and certain SPS/ LPS), helping maintain color and polyp extension.
- Aids macroalgae growth in refugia – potassium is a macronutrient for macroalgae and seagrasses; low potassium can limit growth in refugia used for nutrient export.
- Helps prevent nutrient uptake imbalances – Maintaining proper potassium levels reduces the risk that organisms will be stressed by imbalanced major-ion chemistry when other salts or RO/DI water alter ion ratios.
Coral Essentials recommends the concentration should be between 380 and 450 mg/l (ppm). To ensure healthy coral maintain a dosing plan using our Trace Elements Dosing Calculator as detailed below.
