Pax Bellum LLC was founded in 2007 as a research and development company with a focus on saltwater life support systems. From its inception, the company explored a variety of ways to achieve maximum results balancing water chemistry within closed system hobby aquariums using algae. The ARID system and the technology behind it took 13+ years to develop and refine into the recognizable product it is today. Prototypes for the ARID were trialed extensively on multiple reef systems operated by well-respected and well-known professional aquarists. The first ARID units available for public consumption debuted at MACNA 2017 in New Orleans, Louisiana, and have been popular ever since. All Pax Bellum products are made in Vermont, USA.
