Regulator Bubble Counters
![Bubble counter seal o-ring](/img/guides/bubble-counter/bubble-counter-seal-needle-valve.jpg)
Step 1) Remove the compression collar from the regulator needle valve and put the supplied O-ring on the nipple of the needle valve. The O-ring can be found inside the bubble counter by removing the cap (it may sometimes become stuck to the underside of the cap).

Step 2) Unscrew the top of the bubble and fill 2/3 with 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.

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.
