The ATI Carbo Ex Filter 1.5 Liter is a ready-to-use, single-use cartridge designed to purify the intake air for protein skimmers in saltwater aquariums. It contains one thousand grams of specialized granulate that effectively removes carbon dioxide, cigarette smoke, pollen, and other unwanted airborne substances before they enter your system. By absorbing excess CO2, this filter helps stabilize pH levels at a natural range similar to ocean environments, which is critical for maintaining the health and vitality of sensitive corals while simultaneously suppressing the growth of nuisance algae and cyanobacteria.

This disposable unit comes pre-filled with approximately 1.25 liters of white Carbo Ex special granules and includes an integrated fine dust filter to trap particulate matter from the air stream. The cartridge measures 21 centimeters in height with a diameter of 10.5 centimeters and features versatile hose connections compatible with sizes ranging from 7/10.5 mm up to 10/14 mm, ensuring easy installation on most skimmer models. Users can simply attach their skimmer air hose to the included white central tube adapter and monitor the granule color, replacing the filter once it shifts from white to purple to indicate saturation.

This filtration solution is ideal for reef hobbyists managing aquariums up to approximately 750 liters who are seeking a simple yet effective method to optimize water chemistry without complex chemical dosing. It is particularly beneficial for aquarists struggling with unstable pH levels or persistent algae issues caused by poor air quality in the room where the tank is housed. By ensuring clean, CO2-reduced air enters the skimmer, this product creates a more stable environment that promotes robust coral growth and reduces maintenance stress associated with managing water parameters.
