AF Air Scrubber Medium helps preventing harmful fluctuations in parameters caused by low water pH. The medium is a white, dry pellet. It tightly fills the filter chamber, while allowing air flow. As a result, it perfectly absorbs carbon dioxide. Used and replaced regularly, it guarantees stable pH in the aquarium.

According to our tests, the AF Air Scrubber Medium can raise the pH ~0.2 – 0.4 degrees and its stabilization in the range of 8.0 – 8.4. We recommend using the AF Air Scrubber Medium together with the AF Air Scrubber filter. This configuration ensures the most effective removal of CO2 from the air drawn in by the skimmer. The color changing medium wears out gradually, easily indicating when to replace the cartridge. We recommend replacing it before the color changes completely. The cartridge is meant for single use, cannot be regenerated and reused. Its saturation with carbon dioxide can be recognized by the pellet color. When the cartridge turns purple it means that it absorbed carbon dioxide. Only original CO2 filter cartridges ensure their uninterrupted operation and the highest efficiency. In order to obtain optimal and long-lasting filtration, it is recommended to use AF Air Scrubber Medium together with a dedicated AF Air Scrubber filter.

One package is a full AF Air Scrubber reactor refill 

AF Air Scrubber Media can be used together with Carbon

If used up media is left inside the reactor too long, it can change color again, but it is no longer effective at removing CO2 from the air

When changing out the media, it is best to wear gloves and do it in a well-ventilated space
