The ATI Carbo Ex Air Filter connects to your protein skimmer as a ready to fit filter cartridge to remove unwanted substances via the skimmers air intake line. Suitable for aquariums up to 700lt

It will remove up to 95% of CO2 and most other pollutants such as dust, pollens, smoke etc

The filter lowers the absorbed CO2 concentration so the pH is both raised and stabilised. The growth of corals is then enhanced while the growth of algae & cyano bacteria is limited.

The CO2 absorbing media changes colour from white to blue when exhausted so simply replace with new media.
