Description
A bubble counter is an essential component of a CO2 system. Without one you would simply be guessing at the quantity of CO2 you are dosing into your aquarium, and that makes accurately setting and adjusting your CO2 dosing impossible. A bubble counter solves this problem by enabling you to count how many bubbles per minute you are dosing, and can then make accurate refinements.
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.

3rd Feb 2025The 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.

18th Dec 2024The 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!
