NEW IO Diffuser - Stainless Steel Series - In-Tank CO2 Diffuser

High-Quality Stainless Steel materials for most demanding customers!

The stylish high-quality stainless steel body will give your setup not only the highest dissolution rate but also a touch of luxury.

The World's finest dissolution rate with an easy interchangeable ceramic membrane

In two different sizes;

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

Excellent CO2 dissolution rates thanks to new nano co2 mist technology membrane, easy maintenance and durable materials make IO Diffuser a perfect choice for novice and expert aquascapers alike. Designed to be used as a regular glass CO2 atomizer diffuser, but offering higher CO2 dissolution rates.

An IO Diffuser optimizes the CO2 entering the aquarium for efficient plant absorption and less waste. As CO2 bubbles pass through the porous diffuser, they are diffused into streams of tiny bubbles. With increased surface area, the tiny CO2 bubbles are readily dissolved into the water, increasing the saturation of CO2 in the aquarium ecosystem. 

Diffuser Use

    To use this CO2 atomizer diffuser, simply connect your CO2 tubing to the diffuser.
    It is recommended that you set the pressure on your regulator to a minimum of 2 bar as a starting point. Please allow the diffuser to soak in the aquarium water for at least for 2h before pressurising the diffuser.

    Please note! In the beginning, the diffuser will produce large bubbles around the ring. Over the first 24h of use, all the ceramic pores will fill with water and bubble size will decrease to the optimal size.

    Please allow a few minutes for sufficient pressure to build up to allow the CO2 to begin passing through; it may not begin instantly.
