The Dual Chamber Calcium Reactor is an essential piece of equipment for advanced saltwater reef aquariums. It enhances water chemistry by providing a steady supply of calcium and alkalinity to maintain optimal conditions for coral growth and overall tank health. This reactor features a robust design with the capacity to hold up to 30 pounds of media, making it suitable for large systems of over 1500 gallons. Its built-in recirculation pump ensures efficient flow through the chamber, while adjustable needle valves allow precise control of effluent.
