The ATI ICP Element Cobalt is a liquid supplement specifically designed to maintain optimal cobalt levels in reef aquariums. This essential trace element plays a critical role in the health and growth of corals and other marine life by contributing to their coloration and overall well-being. Each 150 mL bottle contains 60,000 µg of cobalt and is dosed at 1 mL per 100 L (26 gallons) of aquarium water to raise the value by 4 µg/L. The product is compatible with the ATI ICP system for precise monitoring of cobalt levels in reef tanks. It's important to follow the recommended dosage instructions to avoid over-supplementation, which can be harmful to marine life. A single bottle provides a long-term supply, making it ideal for maintaining stable cobalt concentrations throughout the year.
