The CDX Adapter is a specialized fitting designed to create a carbon dioxide adsorption filter for your saltwater aquarium protein skimmer. It facilitates the crucial connection between your skimmer's air intake line and a compatible media reactor, effectively removing atmospheric CO2 before it enters your aquarium water.
Specifically engineered for seamless integration, this adapter is intended for use with TwoLittleFishies PhosBan Reactors and CDX Media. It features precise 1/2 inch by 3/8 inch fittings, ensuring a secure and efficient connection for optimal performance in your reef system.
This adapter is an essential tool for reef aquarists aiming to maintain stable pH levels and improve overall water chemistry in their saltwater tanks. By preventing CO2 from lowering your aquarium's pH, it supports healthier coral growth and a more stable environment, making it a valuable addition for dedicated hobbyists.

I ordered one, everything else in the same shipment arrived, but not this. But this is too inexpensive to re-order or complain about. Then I noticed that the outer-diameter of the smaller (1/4 ? ) tubing fits snugly into the inner-diameter of the 3/8 tubing.
i have an old brs carbon/phos reactor & converted to CO2 scrubber reactor, it's fit perfectly! i'm very happy with my purchase!
Plugs into the Phosban reactor elbow and accepts 1/4 id tubing.
