Aqua Pro External Inline CO₂ Diffuser

Aqua Pro External Inline CO₂ Diffuser

The Aqua Pro External Inline CO₂ Diffuser is designed for planted aquarium enthusiasts who want efficient carbon dioxide diffusion while keeping the inside of their aquascape free from additional equipment. Installed externally along the canister filter's outlet hose, it introduces CO₂ into the flowing water before it returns to the aquarium.

Featuring a fine ceramic diffusion membrane and a durable alloy body, this inline diffuser produces tiny CO₂ bubbles to improve gas dissolution and distribution throughout the aquarium. Its external installation also provides a cleaner, more minimal appearance, making it particularly suitable for carefully designed aquascapes.

✨ Key Features

Fine Ceramic Diffusion: The ceramic membrane breaks CO₂ into ultra-fine bubbles, increasing the contact area between gas and water to support efficient dissolution.

Space-Saving Inline Design: Installs externally on the canister filter's outlet hose, eliminating the need for a conventional diffuser inside the aquarium.

Durable Construction: Combines an alloy body with acrylic and plastic components for a practical, compact design.

Improved CO₂ Distribution: Introduces CO₂ into the filter's return flow, helping distribute dissolved carbon throughout the planted aquarium.

Secure Hose Connections: Designed to connect to compatible filter tubing for convenient installation within an external filtration system.

🌿 Ideal For

The Aqua Pro Inline CO₂ Diffuser is suitable for low-tech-to-high-tech aquascapes where pressurised CO₂ supplementation is required, particularly densely planted aquariums and layouts with demanding aquatic plants.

It is especially useful for aquascapers who prefer a clean aquarium interior without visible glass diffusers or additional equipment attached to the aquarium walls.

🧪 Installation & Usage

Install the diffuser in line with the outlet hose of a compatible canister filter, following the product's inlet and outlet markings. Connect the CO₂ supply line to the designated gas inlet and ensure every hose connection is secure before starting the system.

Select the correct model for your filter hose size:

• EC-16: For 16/22 mm filter tubing.

Allow the ceramic membrane to become fully wetted after installation. Initial diffusion performance may take time to stabilise, so follow the manufacturer's setup instructions before increasing CO₂ output.

⚠️ Important Notes

This product requires a compatible pressurised CO₂ system and suitable CO₂-resistant tubing. Confirm the hose dimensions before purchasing, as the two models are not interchangeable with every filter setup.

Install the diffuser according to the specified water-flow direction. Inspect all connections for leaks and monitor fish and shrimp after adjusting CO₂ delivery. Excessive CO₂ can be harmful to aquatic livestock, even when diffusion is efficient.
