Aquapro Single Stage Compact CO2 Regulator

A good CO2 regulator should be the part of your setup you stop thinking about. Steady pressure, easy to dial in, and compact enough that it never crowds your cabinet. That's exactly what the Aquapro Single Stage Compact CO2 Regulator delivers for planted aquariums of any size.

It runs off a standard CO2 cylinder and gives you precise, repeatable control over your bubble rate, with a dependable 12V electromagnetic solenoid handling your CO2 on and off. Simple to set up, and easy to live with.

Why aquascapers choose it

• Compact gunmetal design. A tidy 8 x 10.5cm aluminium-alloy body, small enough for a nano setup and tough enough to trust on a pressurised bottle.
• Dual pressure gauges. Read your cylinder and working pressure at a glance, so you always know how much CO2 is left and exactly what you're injecting.
• Precision needle valve. Dial in a slow, steady bubble count and it holds its setting, day after day.
• Integrated bubble counter and check valve. Track your dose and stop tank water siphoning back, all built in with no extra inline parts to buy.
• Reliable electromagnetic solenoid. Pair it with any plug-in timer to automate injection around your light cycle for hands-off, consistent dosing.
