Pax Bellum ARID C30 Macro Algae Reactor

The Pax Bellum ARID C30 is a next-generation macroalgae reactor engineered to deliver exceptional nutrient export through rapid Chaetomorpha growth. Its patented coaxial LED lighting system provides intense, evenly distributed PAR for maximum photosynthesis, while vapor heat-pipe technology keeps LEDs cool and prevents excess heat from entering your aquarium.

With system water pushed evenly through the algae mass, the C30 ensures highly efficient uptake of nitrate, phosphate, and CO₂. The result is a powerful, natural filtration system that replaces traditional methods such as GFO, nitrate reactors, bio-pellets, carbon dosing, and even protein skimmers.

Beyond nutrient removal, the ARID system offers unique benefits:
• Stabilises pH day and night
• Maintains high dissolved oxygen levels
• Reduces dissolved CO₂
• Provides a cleaner, more stable environment for reef-tank inhabitants

Designed as a stand-alone filtration system, the ARID C30 helps eliminate equipment clutter while delivering unmatched biological performance.
