Aquario Neo CO2 is an innovative, safe, and cost-effective solution for supplying natural CO2 to freshwater planted aquariums. Unlike high-pressure CO2 systems, which can be dangerous and expensive, or low-pressure alternatives that struggle to support plant growth, Neo CO2 provides a continuous, stable supply of CO2 through the natural metabolism of Saccharomyces cerevisiae bacteria.
Designed for steady photosynthesis, Neo CO2 helps aquatic plants grow healthier and more vibrant over a period of up to 50 days. Its top-fermenting jelly system ensures consistent CO2 production, while stabilized bacteria and a special culture medium maintain efficiency. The set includes everything needed — hose, bottle, and the world-class Neo Diffuser for fine, uniform bubbles. The system is also reusable: simply refresh the solution with the refill pack to restart CO2 generation.
