Two Little Fishies CDX 750 mL Carbon Dioxide Adsorption Media

  • $ 16.95


Many aquariums suffer from low-pH issues. Sometimes it’s the carbon dioxide that accumulates in the air in closed buildings that won’t let the pH of your aquarium stay up. Two Little Fishies have the solution: It’s 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 Adaptors. The CO2-free air injected into your protein skimmer drives off the excess CO2 dissolved in the water, so the aquarium’s 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.
