About this product

The AquaLabs Pro Inline CO₂ Diffuser delivers ultra-efficient CO₂ dissolution directly into your aquarium's water flow — without a single bubble entering the tank. Designed for planted aquarium enthusiasts who demand clean aesthetics and maximum CO₂ uptake, the Pro model features an upgraded diffusion chamber and precision-engineered internals for superior performance over standard inline diffusers. Simply cut the outlet hose of your external canister filter and secure the unit in place. Available in 12/16mm and 16/22mm to suit a wide range of canister filter setups.
