The ATI Element Rubidium is a liquid supplement designed to increase rubidium levels in saltwater reef aquariums. This product can be used directly to raise the current value of rubidium by 5 µg/L for every 1 mL added per 100 liters (26 gallons) of water, making it easy to adjust and maintain optimal conditions for your marine life. Each bottle contains a significant amount of rubidium—75,000 µg—and is compatible with the ATI ICP system, allowing you to monitor and manage trace element levels effectively.
