Dymax Nano Co2 Diffuser MD-107

CO2 is arguably the most important element in the planted aquarium. It is required for respiration and growth by all aquatic plants, used in a process called photosynthesis.

So, when only the best will do the Damax range of Aquascaping and planted tanks brings you the best range in equipment.

The Dymax Nano CO₂ Diffuser MD‑107 is an innovative diffuser/reactor designed for mini planted aquariums to achieve effective CO₂ diffusion without unnecessary wastage. It works by combining the incoming water flow with CO₂ gas inside a reaction chamber, creating a vortex-style mix that collides with the internal bio balls to maximise dissolution efficiency before the water exits the bottom. Faster dissolution helps your CO₂ last longer and improves distribution through the tank compared to inefficient bubble release.

This unit requires a separate small pump/powerhead (not included) to drive water through the chamber, plus your CO₂ supply and tubing. It includes suction cups and bioballs, and is marketed as suitable for aquariums up to 120 cm in length (flow and aquascape will influence real-world performance).

Key features

• Vortex reaction chamber design for efficient CO₂ diffusion.​
• Bioballs included to increase mixing and dissolution efficiency.
• Helps reduce “wasted” undissolved CO₂ by dissolving gas faster.
• Requires pump/powerhead + CO₂ supply (not included).
• Recommended for aquariums up to 120 cm (manufacturer/retailer guidance).
