AquaPro Neo CO2 Diffuser
The AquaPro Neo CO2 Diffuser is a compact, high-performance diffuser designed to efficiently dissolve injected CO2 into the water of planted aquariums. Its fine-pored diffuser membrane produces a mist of extremely small CO2 bubbles, increasing contact time with the water and helping plants receive the carbon dioxide they need for strong, healthy growth.
With its clean, minimal design, the Neo CO2 Diffuser blends discreetly into an aquascape while delivering efficient CO2 distribution. It is an excellent addition to pressurised CO2 systems where effective diffusion and a tidy appearance are priorities.

I’ve used the AquaPro Neo CO2 Diffuser in my 150-liter tank for three months. The plants have grown much more vigorously, especially the stem plants and mosses. The diffuser is quiet and looks clean in the tank. No visible bubbles escaping, which is a big plus.

The CO2 mist is very fine and consistent. I noticed better color development in my red and green plants. It fits well in my aquascape without being noticeable. Only minor adjustment needed to the flow rate.

After switching from a basic diffuser, my aquarium has seen a noticeable improvement in plant health. The Neo diffuser dissolves CO2 more evenly and keeps the water stable. Easy to install and maintains a clean look.
