Unit is supplied complete with 0.5kg of colour-changing media
- Struggling with low pH? Frustrated by slow coral growth? The Wavereef colour-changing CO2 absorbent media is a great solution.
- The way it works is simple: just attach 9/12mm tubing to the air intake on your skimmer. Then connect the other end to the CO2 scrubber and you are ready to go. Now you will be able to raise the pH of your aquarium and control carbon dioxide.
- When the media turns white or your pH drops, then it is time to replace the media.
