Product details
Carbon Dioxide Adsorption Media – Two Little Fishes is CO2 adsorption media designed for aquarium pH management in reef setups. It’s used inside a tall, column-style reactor (such as a PhosBan reactor or similar) and is connected to a protein skimmer’s air intake. In practical use, the media helps remove carbon dioxide from air drawn into the skimmer, and the skimmer’s CO2-free air can also help reduce dissolved CO2 in the aquarium water, which may support a higher average pH.
Features:
- CO2-adsorbing filtration media intended for use in PhosBan-style reactors or similar aquarium reactors
- Helps tackle pH-lowering CO2 by targeting carbon dioxide entering the protein skimmer
- Works with protein skimmers connected to a reactor filled with CDX media
- Color indicator helps track exhaustion: media turns from white to violet as it becomes spent
- Replace exhausted media when the color change indicates it has been depleted
Specifications:
- Media form: CO2 adsorption media for reactor use
- Recommended reactor type: Tall columnar reactor (e.g., PhosBan reactor or similar) used with a protein skimmer air intake
- Capacity (reference listing): 750 ml
- Weight (reference listing): 685 g
