The bubble counter 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 Strideways 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 cylinder.
Instructions
- Unscrew the top cap and fill 3/4 with water.
- 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.

Great service from Bluviva as expected. I have attached it to the Strideways CO2 regulator and all is well.
