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.

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.

Well made, easy to use. NOTE: there's a little O-ring inside the bubble counter which has to be installed on the needle valve before screwing on the bubble counter. Well made, easy to use.

Easy to use, but just remember to fit the little O-ring that's inside the bubble counter to the needle valve before screwing on. I didn't and it caused a leak. That'll teach me for not reading the instructions! Easy to use, but just remember to fit the little O-ring that's inside the bubble counter to the needle valve before screwing on.

Easy to use and great for getting the CO2 level / dosing set to the right level in conjunction with the drop checker (also in the kit I ordered). Easy to use and great for getting the CO2 level / dosing set to the right level in conjunction with the drop checker (also in the kit I ordered).
