CO2 skimmer absorber

CO2 absorber for protein skimmer, pH stability and optimized air

The CO2 absorber for protein skimmer is an accessory designed to improve the quality of the air drawn in by the skimmer. By filtering out ambient carbon dioxide, it allows air with a lower CO2 content to be injected into the reaction chamber, which directly helps raise and better stabilize pH in the reef aquarium.

Its use has grown with the widespread adoption of reef tanks in enclosed environments, where indoor CO2 levels can be high. The first systems appeared alongside the development of modern skimmers and the increasing demand for chemical stability.

Easy to install, the CO2 absorber generally works with specific media based on soda lime. It is an effective solution for limiting pH drops, improving coral comfort, and optimizing the skimmer’s overall performance.
