ATI Carbo Ex Filter 4 L – Refillable CO₂ filter for reef aquariums

The ATI Carbo Ex Filter 4 L is an air filter specially designed to reduce carbon dioxide (CO₂) present in the air drawn in by your marine aquarium skimmer. Supplied ready to use with 2.6 kg of Carbo Ex pellets, it provides an effective solution to help stabilize pH and improve conditions for coral growth.

With a filtration capacity of 4 L, this refillable anti-CO₂ filter is particularly suitable for large reef aquariums. ATI recommends it especially for setups starting at around 750 L.

Why use an anti-CO₂ filter in a reef aquarium?

In homes, carbon dioxide levels can rise due to the respiration of occupants and insufficient air exchange. When the skimmer draws in this CO₂-rich air, gas exchange can contribute to maintaining a lower pH in the aquarium.

The ATI Carbo Ex 4 L filter acts directly on the skimmer’s air intake. Its filter media absorbs part of the CO₂ before the air comes into contact with the aquarium water.

Promote coral growth and vitality

By reducing CO₂ input, the Carbo Ex filter can help support a higher and more stable pH. This stability helps create favorable conditions for calcification and the development of reef-building corals, including Acropora, Montipora, and other SPS and LPS corals.

According to ATI, this improvement may also help limit the growth of certain unwanted algae and cyanobacteria. Results, however, still depend on the characteristics and biological balance of each aquarium.

Benefits of the ATI Carbo Ex 4 L filter

Complete air filtration

The Carbo Ex pellets are designed to absorb carbon dioxide as well as certain unwanted substances present in the air drawn in by the skimmer, such as pollutants associated with cigarette smoke or pollen.

A fine dust filter is also integrated to retain dust particles present in the incoming air.

A refillable and economical filter

Unlike disposable models, the ATI Carbo Ex Filter 4 L has a reusable body. When the pellets become saturated, simply replace the filter media without changing the entire filter.

The color change of the pellets makes monitoring easy: the media gradually changes from white to purple when saturated and needs to be replaced.

A ready-to-install system

The filter is supplied already filled with its absorbent media. It connects directly to the skimmer air intake hose, without requiring an additional pump.

Installing the ATI Carbo Ex 4 L filter

How do you connect the Carbo Ex to your skimmer?

Installation is simple. Place the filter near your skimmer in a stable location protected from splashes.

Then connect the skimmer air intake hose to the white central tube of the Carbo Ex filter. The drawn-in air then passes through the absorbent media before feeding the skimmer.

Make sure the hose is properly connected and that airflow is not obstructed. The filter works thanks to the skimmer’s natural suction.

When should the Carbo Ex pellets be replaced?

The pellets should be replaced when their color changes from white to purple. This change indicates that their CO₂ absorption capacity is exhausted.

Service life varies depending on factors such as the CO₂ concentration in the room, the amount of air drawn in by the skimmer, and operating conditions.

To refill your filter, ATI recommends ATI Carbo Ex Media 4 L pellets, reference 2540001, sold separately.

The product includes a 4 L refillable filter body, an initial charge of 2.6 kg of Carbo Ex absorbent pellets, and an integrated fine dust filter.

Usage precautions

The absorbent pellets are active chemical products and must be handled with care. Avoid contact with skin and eyes as well as inhalation of dust. Use gloves and eye protection when replacing the media, and keep the product out of reach of children.

Carbo Ex is intended exclusively for air filtration. The pellets must not be introduced directly into aquarium water.
