Description
GLA External CO₂ Diffuser Atomizer (Inline)
The GLA External CO₂ Diffuser is an inline CO₂ diffusion device designed for installation outside of the aquarium. It installs directly into the outflow tubing and may be mounted horizontally or vertically, allowing flexibility to suit different plumbing layouts and cabinet configurations.
The diffuser features a waterflow resistance-free internal design with a large internal chamber that allows water to pass through freely without restriction. Unlike many inline diffusers that rely on narrow passages or column-style ceramic elements, this design minimizes flow loss while maintaining effective CO₂ diffusion without compromising filter flow.
CO₂ Diffusion Performance
A large ceramic diffusion membrane provides a wide gas output area, producing fine, dense, and uniform CO₂ microbubbles. The expanded diffusion surface improves dissolution efficiency while reducing the formation of larger bubbles commonly associated with smaller or restrictive inline diffusers.
The ceramic membrane is replaceable, allowing consistent long-term performance and straightforward servicing.
Visual Monitoring Window
A built-in clear visual window allows users to easily confirm that the diffuser is operating correctly. Bubble formation and CO₂ output can be verified at a glance without disconnecting hoses or removing the unit from service.
Construction & Serviceability
- Rigid aluminum housing secured with screw-fastened assembly for a leak-resistant seal
- Designed for long-term external use
- Fully disassemblable for thorough cleaning and maintenance
- Ceramic membrane is accessible for cleaning or replacement
The diffuser can be separated into individual components, simplifying maintenance and extending service life.
The GLA External CO₂ Diffuser provides efficient inline CO₂ diffusion with minimal impact on water flow. Its resistance-free internal design, replaceable ceramic membrane, visual monitoring window, and serviceable construction make it a reliable solution for planted aquariums requiring external CO₂ diffusion.
