Aquatop In-line CO2 Diffuser for Canister Filters

The Aquatop In-line CO2 Diffuser efficiently delivers CO2 into large or high flow aquariums. Made from a durable plastic, the IL-CO2 is easy to install and works in-line with your canister filter tubing. The highly porous ceramic atomizer diffuses CO2 so that it can be readily dissolved into the water column, increasing the saturation of CO2 which is then easily absorbed by live plants.
