This Carbon Dioxide Absorption Media takes care of pH management at the source for water parameters vital for healthy reef aquariums. It helps maintain and bring up aquarium pH by removing carbon dioxide brought in through protein skimmers. Sometimes the carbon dioxide that accumulates in the air in closed buildings won't let your aquarium pH stay up. This is the solution.
- Helps keep pH-lowering CO2 out of your aquarium
- CO2 absorbing media for PhosBan Reactor or similar aquarium reactors
- Easy to use
- 750 ml lasts 6-8 weeks average
Directions For Use:
Install CDX in a tall columnar reactor such as Two Little Fishies PhosBan Reactor. Connect the air intake for the protein skimmer to the outflow pipe of the reactor using the Two Little Fishies CDX Adaptor or a similar barbed reducing fitting. CDX contains a harmless indicator dye that turns violet when the media is saturated with CO2. This color will change in layers that start at the bottom. When the CDX media near the top turns violet, it is time to replace the CDX media.
