Pax Bellum Arid C30 Reactor



This innovative algae reactor provides reef keepers with the ultimate tool to export nutrients and maintain nitrate and phosphate at levels required for vigorous SPS coral growth. The ARID is a work of art and it’s patented design is based on more than a decade of research and development. As an option, you can order a Ca Reactor Feed/Injection Assembly to send excess CO2 from your calcium reactor right into the ARID, further benefiting macro algae growth.  Includes quick disconnects. Light Tube should be replaced after 10-12 months.
