The Two Little Fishies CDX is a specialized carbon dioxide absorption media designed to address the issue of excess CO2 in saltwater aquariums, which can lead to low pH levels. When installed inside a PhosBan reactor and connected to a protein skimmer's air intake, it effectively removes dissolved CO2 from the water, helping to stabilize and increase the pH level. This product is available in two sizes: the 3-liter option provides extended use for larger aquarium setups, ensuring optimal conditions are maintained over an extended period.
