Description

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.

In the box

Regulator with integrated bubble counter, electromagnetic solenoid, 12V power adapter (NZ/AU plug), a spare O-ring, and a syringe for filling the bubble counter. Everything you need to get CO2 running on your tank.

Backed by a 1 year warranty and friendly local NZ support. Order yours today and keep your planted tank growing with steady, reliable CO2.

Great regulator and amazing support

Really easy to operate, even as a beginner. The regulator feels solid and the gauges are easy to read. I also really appreciate Aquascape’s support, they answered all my questions and gave me helpful tips about precautions, things to look out for, and how to safely manage the CO₂ system. That support made me feel much more confident using CO₂ for the first time. Definitely happy with both the product and the service!

I have had this regulator for about a week now. I put it on a timer so it starts 1 and a half hours earlier than my light. Every morning that I wake up the bubble count is different. I have caridina shrimp, who are extremely sensitive to co2 changes. So I have started my bubble count at 1 drop per 4 seconds, and with monitoring have increased it to 1 drop every 3 seconds. The last few morning that I woke up it was at 1 drop every 10-15 seconds which is not anything for a 50L tank so it did not bother me that much. This morning I woke up to 1 drop every 0.6 seconds. That is enough to kill everything in my tank, I am glad I caught it when I did but that is not ok. It should not start dumping co2 like that. Plus it is very fiddly to get it set to a low drop rate like 1 drop every 4-5 seconds but once you pass the 1 drop every 3 seconds threshold it becomes easier to set up.

Great value regulator

Great value regulator. No need for anything more complex for our 1 tank setup. Thanks for the advice and help. Only thing I would say is that the adjustment (bubble count) can seem to vary until the pressure settles in the line and diffuser and can be a little sensitive when trying to make fine adjustments to the flow.

do you ship to Australia? Can you tell me the items i need to buy for a complete Co2 setup? I find it a little confusing to know what I need.

The Aquascape Shop

Yes we do, use the bundle builder - if that still doesn’t work for you - we’re happy to get on a call.

I'm looking at buying this regulator for my aquarium but concerned about it fitting in the cabinet under my tank. Is there any way you could measure the total height connected to a D size / 6L CO2 cannister?

The Aquascape Shop

The height of this regulator from the top of the bubble counter to the bottom is 12.9cm +/-1cm. The bit that attaches to the regulator is 3cm.

So it should protrude 9.9cm above your valve.

hope this helps.
