UNS Pro Inline CO2 Diffuser - Small

The Ultum Nature Systems Pro Inline CO2 Diffuser delivers consistent CO2 injection for healthy aquarium plant growth while reducing visible equipment. Designed to install directly into your canister filter’s outflow line, it diffuses CO2 efficiently and discreetly. This makes it one of the best CO2 diffusers for aquascapers who enjoy a clean view and less equipment in their planted tanks. Unlike other inline diffusers on the market, the ceramic disc on the UNS Pro is side-mounted. This small detail reduces flow disruption and makes it easy to clean or replace the disc when needed.
