Pax Bellum ARID N24 Macroalgae Reactor

The concept of using macroalgae as a method of nutrient export is not new. However, the introduction of the ARID (Algae Remediation Illuminated Device) the original, patented macroalgae reactor by Pax Bellum is a quantum leap forward. This ingenious device utilizes macroalgae (specifically Chaetomorpha) to function as a tunable nutrient export mechanism. The unique design of the ARID incorporates a coaxial LED light tube to maximize light penetration and efficiency. The tube and flange design of the device serves to isolate the algae from atmospheric CO2, which effectively limits the carbon source for the algae to only that which is respired by organisms within the aquarium. This is a self regulating feature and eliminates organic carbon buildup (yellowing of the water). The ARID is analogous to a lung for the aquarium, by supersaturating the aquarium with oxygen created by the algae during its respiration while removing excess CO2. Pax Bellum recommends running the ARID on a "reverse
