Carbon Dioxide Absorption 750ml

When carbon dioxide accumulates in the air in closed buildings, the pH of an aquarium won't stay up. We have the solution: it’s called CDX, a Carbon Dioxide adsorption system. 

Simply install CDX in our PhosBan reactor and connect it to the air intake of a protein skimmer, using a length of hose and our CDX adaptor to make the connection. 

The CO2-free air entering the protein skimmer soaks up excess CO2 dissolved in the aquarium water and the aquarium’s pH rises.

A 750 ml jar will last about 6-8 weeks on the average 50 - 100 gallon reef aquarium.

You can tell when it is exhausted because it changes from white to pink.
