Carbon dioxide (CO2) levels can have a direct affect on your aquarium pH, seriously impacting coral growth and the overall health of your system. The Aquaforest AF Air Scrubber reactor and absorbing media help prevent harmful fluctuations caused by low pH due to high CO2 concentrations.

  • Reduces CO2, increases pH
  • Stabilizes day/night pH levels
  • Prevents usdden changes in dKH
  • Compatible with a variety of skimmers
  • Easy to use, assemble, & disassemble
  • High-quality acrylic construction


The body of the AF Air Scrubber reactor is made of the highest quality white and transparent acrylic. The base of the reactor contains three cut-to-size sponges which are designed to be soaked in RO water to moisten the air and improve media performance. Lab tests indicate this design significantly extends the life of the media, giving you more bang for your buck over time.


By designing the AF Air Scrubber  to pull CO2 filled air through the sponge layer at the bottom, the air is channeled up through a grid making sure the highest amount of CO2 can be removed before going into the skimmer or reef aquarium. The media is protected between a layer of special dust absorbing sponges at the top and bottom of the reactor. On the lid of the reactor, there is a cap with a smart-twist closure allowing for quick and easy access to the interior of the reactor. To ensure proper airflow suction, a flap and seal has been installed to guarantee bottom to top airflow. As a result, the color changing media is gradually used from the bottom to the top making it easy to see when it is time to replace the media. It is recommended to replace the media before the color completely changes. On the outer part of the lid, there is a 10 mm/⅜” hose connection, which connects the reactor to a protein skimmer. Within a few days, signs of the media working will be apparent and pH will increase as CO2 is being absorbed.


The AF Air Scrubber can raise the pH ~0.2 – 0.4 degrees and its stabilization in the range of 8.0 – 8.4. It is recommended to use the Aquaforest AF Air Scrubber together with the Aquaforest AF Air Scrubber Media cartridge to ensure the most effective removal of CO2 from the air drawn in by the skimmer.
