Description
Description
The Week Aqua Stainless Steel Extended CO2 Diffuser is built for aquascapers who want efficient CO2 dissolution without an intrusive bit of kit hanging in the tank. Its extended stainless steel stem reaches well below the waterline and tucks neatly against the glass, while the nano-ceramic diffuser disc breaks CO2 into an exceptionally fine, uniform mist for maximum absorption and healthier, more vibrant plant growth.
A built-in quick-connect check valve sits inline on the CO2 line: push the tubing in to lock it, pull the collar to release. The automatic locking mechanism holds the connection securely and prevents water from being drawn back up the line when your CO2 shuts off.
Finished in corrosion-resistant 304 stainless steel, it's designed to sit unobtrusively in rimless tanks and resist clouding or rust over the long term.
Key features:
- Nano-ceramic diffuser disc — high-density ceramic produces an ultra-fine, dense bubble mist for excellent CO2 saturation
- Quick-connect check valve — push-to-connect, pull-to-release, with an automatic locking mechanism and built-in backflow prevention
- Extended stainless steel design — long stem reaches deep into the water column; sleek, low-profile look suits rimless aquascapes
- Corrosion-resistant — premium stainless steel construction built to last
- Four sizes — 25 cm, 30 cm, 35 cm and 40 cm to suit a range of tank depths
- Easy mounting — includes suction cups for secure, adjustable positioning
Installation:
- Soak the diffuser disc in water for about 30 minutes before first use for the finest bubble size.
- Connect CO2-resistant tubing to the quick-connect check valve — push the tubing fully home until it locks.
- Mount the diffuser in the tank using the suction cups, ideally in an area with moderate flow to carry the mist around the aquarium.
- Open your CO2 and adjust your regulator to a steady working pressure, then dial in your bubble rate.

- Lengths available: 250 mm / 300 mm / 350 mm / 400 mm
