Pax Bellum ARID N24 Macro Algae Reactor
The Pax Bellum ARID N24 is a high-performance nano/mid-size macroalgae reactor designed to efficiently remove excess nitrates and phosphates from reef and marine aquariums. Utilizing Chaetomorpha macroalgae as a natural nutrient export mechanism, the N24 stabilizes pH, reduces dissolved CO₂, and maintains optimal oxygen levels, creating a healthier environment for corals, fish, and invertebrates.
Equipped with a coaxial LED light array and vapor heat-pipe technology, the N24 delivers intense photosynthetic light while keeping LEDs cool and maximizing efficiency. This compact yet versatile reactor can replace multiple filtration devices, including GFO, nitrate reactors, bio-pellet reactors, carbon dosing systems, and protein skimmers. Its premium cast acrylic construction with polished edges and magnetically removable light cover allows easy inspection and maintenance of the macroalgae mass.
