Description

Want high performance with minimal visual clutter? This inline CO₂ bundle keeps the gear in the cabinet and the scape in the spotlight. CO2Art is known for precision CO₂ hardware designed specifically for planted aquariums—reliable, tidy, and built for daily use.

At its core, the CO2Art PRO-SE dual-stage regulator (W21.8 / AU–NZ Type 30) delivers stable output from full cylinder to near empty. It features an integrated solenoid for effortless on/off control, a medical-grade needle valve for ultra-fine adjustments, and a bubble counter with built-in check valve to protect your system and make tuning a breeze.

CO₂ is dissolved efficiently via the CO2Art inline diffuser, plumbed into your canister filter return—so you get fine-mist dissolution and a crystal-clear display with no in-tank disc. The glass drop checker kit helps you dial in levels at a glance, while the clear, rigid polyurethane CO₂-resistant tubing (choose 3 m or 6 m) gives a neat, durable run from cylinder to cabinet hardware.

Compatibility notes

For use with pressurised CO₂ cylinders using W21.8 (AU/NZ Type 30) valve threads.
Install the inline diffuser on the filter outflow (return) line.
Use only CO₂-rated tubing and secure all connections.

Quick setup tips

Install the regulator securely on the cylinder and check all fittings.
Open the cylinder valve slowly.
Set working pressure to 30–40 psi for the inline diffuser.
Run CO₂ 1 hour before lights on and switch off 1 hour before lights out.
Bubble rate depends on tank size — adjust gradually using the drop checker.

Built for aquascapers who want CO2Art precision, clean lines, and reliably dissolved CO₂—out of sight, very much in effect.
