Skim AEROX Ultra‑Pure Spheres CO₂ Scrubber Media
Professional product description:
Skim AEROX Ultra‑Pure Spheres CO₂ Scrubber Media is a specialised, ultra‑pure medical‑grade formulation explicitly developed for reef aquariums. Used on the protein skimmer air intake, it efficiently removes CO₂ from incoming air, helping to create a more stable and optimised environment for sensitive and demanding corals.
By reducing CO₂ in the skimmer intake air, Skim AEROX helps to:
- Stabilise and elevate aquarium pH, improving overall system chemistry
- Reduce pH fluctuations between day and night, promoting a more consistent and less stressful environment for all inhabitants.
- Support coral growth, colour and calcification in SPS, LPS and soft corals
- Reduce the likelihood of nuisance algae and cyanobacteria by improving pH stability and limiting CO₂‑driven imbalances
The spherical media granules feature a convenient white‑to‑violet colour change that clearly indicates when the media is becoming exhausted, making maintenance straightforward and predictable.
Recommended use:
Place 750–1000 ml of Skim AEROX in a suitable CO₂ scrubber reactor connected directly to your skimmer’s air intake. In a 500–750 L reef aquarium, the media is typically effective for 4–6 weeks, depending on room CO₂ levels and skimmer airflow. Monitor both the colour of the media and your aquarium pH to determine the optimal replacement interval.
Important notes:
- Designed exclusively for use in air on the skimmer intake
- Do not use directly in aquarium water
- Reseal the zip‑bag tightly after opening
- Store in a cool, dry place to maintain performance
Skim AEROX Ultra‑Pure Spheres CO₂ Scrubber Media offers a professional‑grade solution for reef aquarists seeking more stable pH, reduced day–night pH swings, enhanced coral health, and fewer issues with cyanobacteria and nuisance algae.
