The Arid C36 Macroalgae Bio Filter is a revolutionary device designed to enhance water quality in saltwater aquariums by utilizing macroalgae for nutrient export. It features a coaxial LED light tube that maximizes light penetration and efficiency, promoting robust growth of Chaetomorpha algae. This unique design isolates the algae from atmospheric CO2, ensuring that carbon sources are limited exclusively to those respired within the aquarium, effectively preventing organic carbon buildup. The Arid functions as an oxygenating lung for your reef tank by supersaturating it with oxygen produced during photosynthesis while removing excess CO2. It is ideal for experienced aquarists looking to precisely manage nutrients such as nitrogen and phosphate in their reef ecosystems.
