The Chihiros External CO₂ Diffuser is a high-efficiency inline diffuser designed to deliver exceptionally fine CO₂ mist directly through your filtration system. Installed on the outflow of a canister filter, it maximizes CO₂ dissolution by using the filter’s water pressure to atomize gas into ultra-fine bubbles, ensuring superior absorption and stable CO₂ levels throughout the aquarium. This external placement keeps the tank interior clean and unobstructed, making it ideal for minimalistic or high-end aquascapes. Built with durable materials and engineered for consistent performance, the Chihiros External CO₂ Diffuser enhances plant growth, supports vibrant aquascapes and maintains optimal CO₂ distribution without adding visible equipment inside the display.
