Carbon Dioxide Absorption 3L*

Many aquariums suffer from low-pH issues. Sometimes its the carbon dioxide that accumulates in the air in closed buildings that wont let the pH of your aquarium stay up. Two Little Fishies have the solution, Its called CDX, a Carbon Dioxide adsorption system.

Simply install CDX media in a PhosBan reactor and connect it to the air intake of your protein skimmer with the CDX Adaptor. The CO2-free air injected into your protein skimmer drives off the excess CO2 dissolved in the water, so the aquariums pH rises. Happy days are here again!

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.
