Upgrade your aquarium’s CO₂ system without the hassle.

Unlike traditional in-line diffusers that require cutting your external filter hose and complicated maintenance, the Neo Mixer installs directly onto the outlet of your external filter — no cutting required.

Powerful CO₂ Dissolution

Installed at the outlet, the Neo Mixer uses the natural force of water flow to maximize CO₂ bubble dissolution. When paired with the Neo Diffuser Tiny, it delivers outstanding efficiency, helping your plants thrive.

Included at no extra cost:

• Neo Diffuser Tiny

• Round flow-control parts (as shown)

Easy Maintenance

The Neo Mixer is designed for convenience:

• Quick attachment and detachment from the outlet

• Removable diffusion ceramic for simple bleach cleaning

• No need to disconnect or modify filter tubing

Designed for Clean Aquascapes

To maintain the beauty of your layout, both left- and right-side mounting options are included for flexible installation.

Round flow-control parts are also provided to reduce water speed and further enhance CO₂ diffusion performance.

Wide Compatibility

• Compatible with Neo Flow (Version 1 & 2)

• Works with Neo Skimmer and Relievers

• Can be connected to external filters from other brands

When used together with the Neo Skimmer, the Neo Mixer maintains full skimming performance while creating three stages of water flow transformation — increasing CO₂ solubility even further.
