Bubble Counter Setup Instructions

Regulator Bubble Counters

Bubble counter seal o-ring
Step 1) Remove the compression collar from the regulator needle valve and put the supplied O-ring on the nipple of the needle valve.
Screw the bubble counter onto regulator needle valve
Step 2) Fill the bubble counter 2/3 full with tap water and screw it onto the needle valve. Tighten firmly to ensure an air-tight seal. You may wish to check the seal is 100% air-tight using soap suds once the system is operational.
Attach tubing to the bubble counter
Step 3) Unscrew the compression collar from the bubble counter, feed the tubing through it and onto the nipple of the bubble counter.
Tighten the bubble counter compression collar
Step 4) Tighten the compression collar using manual force only (no tools).
Adjust needle valve for CO2 dose
Step 5) Adjust the flow rate using the needle valve. Anticlockwise to increase flow, clockwise to decrease flow.

Step 6) Use the regulator's needle valve to adjust flow rate.

Count the number of bubbles going through the bubble counter and adjust the flow accordingly.

A good starting point is 1 bubble / second for a 150L aquarium.
