Glass Inline CO2 Diffuser
$20.00
A glass inline CO2 diffuser that connects directly to your external filter tubing, using a ceramic disc for fine, efficient CO2 diffusion — completely hidden from view inside the tank. Available in 12/16mm and 16/22mm sizes.
Achieve efficient, bubble-free CO2 diffusion with the TNA Glass Inline CO2 Diffuser. Designed to be plumbed directly into your external canister filter’s outflow line, this diffuser uses a ceramic diffusion disc to break CO2 gas into a fine mist of micro-bubbles as your filter’s water flow passes through it — maximising contact time and dissolution efficiency before the water re-enters your aquarium.
Because it sits inline with your existing filter tubing rather than hanging inside the tank, the TNA Inline Diffuser keeps your aquascape completely free of visible equipment, giving you a clean, unobstructed view of your planted tank.
Key Features
- Inline installation — connects directly into external filter tubing
- Ceramic diffusion disc breaks CO2 into fine micro-bubbles for maximum dissolution
- Crafted from clear glass for a clean, unobtrusive look with no visible equipment in the tank
- No hanging hardware or in-tank placement required
- Available in two sizes to fit different filter tubing diameters
Available Sizes
- 12/16mm (fits standard 12mm ID / 16mm OD tubing)
- 16/22mm (fits standard 16mm ID / 22mm OD tubing)
(Please check your external filter’s inlet/outlet tubing diameter before choosing a size)
Why Choose an Inline Diffuser
- Eliminates visible diffusers, drop checkers, or bubble counters cluttering your aquascape
- Uses your existing filter’s flow rate to drive CO2 dissolution — no extra pump or powerhead needed
- Glass construction won’t cloud, discolour, or leach chemicals over time
- Ceramic disc provides fine, consistent micro-bubble diffusion for efficient CO2 uptake by plants
Installation Note
Install by cutting into your external filter’s outflow tubing at a convenient point and connecting the diffuser inline. Ensure the correct size is selected to match your tubing diameter for a secure, leak-free fit.
Ideal For
CO2-injected planted aquariums using external canister filters, aquascapers wanting a clutter-free tank with no visible diffusion equipment, and anyone looking to upgrade from a standard in-tank diffuser to a more efficient inline solution.
