NEW IO Diffuser – Acrylic Series – In-Tank CO2 Diffuser

The World’s finest dissolution rate with an easy interchangeable ceramic membrane.  The sturdy acrylic body protects from cracks and damages.

In two different sizes;

• Small for aquariums below 150 L
• Large for aquariums above 150 L

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 aqua-scapers 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 pressurizing 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.
