The ATI Carbo Ex 4L is a refillable air filter that connects to your protein skimmer. It removes up to 95% of CO2 and fine particles that can creep into your air supply, such as dust and pollens.
The CO2 absorbing media changes colour from white to blue when it has exhausted its purpose and on this 4L unit, the CO2 absorbing media can be purchased separately in 3250g packs when required.
The removal of CO2 will help to raise and maintain a stable pH value, which is highly beneficial to the overall health of your aquarium. It can aid in improving coral health and growth and is an effective preventative measure for stopping airborne pollutants from entering the aquarium.
The lack of CO2, which will be aided by your Carbo Ex Air Filter, will also help to eliminate algae growth- including black hair algae and Cyano!
