IO Diffuser Replacement Ceramic Membrane is designed for the easy reinstallation of the old membrane of our New IO  Acrylic Series Diffuser and New IO Stainless Steel Series Diffuser. Or simply to have a spare t maintenance time

The possibility of replacing the ring allows the optimum performance of the IO diffusers for years of use.

The membrane is made with Nano CO2 Mist Technology providing you with the highest dissolution rates. Carbon dioxide passing through the porous ring is readily dissolved into aquarium water in the form of tiny bubbles because of the increased surface area. The IO diffuser optimizes the amount of CO2 entering the aquarium for the most efficient absorption and less CO2 waste.

Depending on your IO diffuser size (and the tank size) you can choose between two options:

• Small for tanks below 40G
• Large for tanks above 40G
