CO2 Bubble Counter & Integrated Check Valve For Regulators
Key Facts
- Essential component of any CO2 system.
- Accurately monitor and adjust your CO2 dosing.
- Attaches directly to a regulator's needle valve.
- In-built check valve prevents water siphon / back-flow.
- Fits 4/6mm Tubing.
- 1/8" NPT female thread.
- Easy viewing of bubbles.
Description
The bubble counter also has an in-built check valve to prevent water siphoning from your aquarium and into your sensitive (and expensive) components such as solenoid or regulator. Once water has entered these components it is difficult to remove, and can cause complete blockage or inconsistent output. Therefore, eliminating the possibility of that from occurring is essential.
This bubble counter screws directly onto the needle valve of your regulator. The tubing attaches to the opposite end.
The bubble counter must be vertical to allow the bubbles to float upward - please therefore ensure your regulator/needle valve will allow this configuration when attached to your gas cylinder. If not, an Inline Bubble Counter can be used instead, which has tube connection fittings at each end.
Instructions
- Unscrew the top cap and fill 3/4 with water (tap water is fine).
- Firmly screw the top back on.
- Ensure O-ring is correctly position at the bottom of the threads in the well at the bottom of the bubble counter.
- Screw the bubble counter onto the needle valve.
- Unscrew the compression collar from the top of the bubble counter.
- Feed tubing through the collar and firmly tighten to hold the tubing in place.

The bubble counter is well made and works efficiently. The top sealing washer was missing, there is a good chance that it fell out during my assembly and was lost. I emailed CO2 Supermarket about it, who very kindly sent a replacement straight away. Excellent service. The bubble counter is well made and works efficiently.

The construction feels solid, and it's doing its job perfectly. Just make sure you put the O-ring in properly to avoid leaks - I learnt that the hard way!

Does what it's supposed to without any fuss. the integrated check valve is great for keeping water out of the regulator. No leaks or issues. Does what it's supposed to without any fuss. the integrated check valve is great for keeping water out of the regulator. No leaks or issues.
