Bubble counter and Beetle counter are used for Co2 measurement in the aquarium. Ideally, the planted tank should have between 1 and 2 bubbles per second added to the water column while the aquarium lights are on. In order to properly count bubbles, take a stopwatch for 10 seconds and count the bubbles that occur during that time period. After 10 seconds have passed, divide the number you counted by 10 and you will have your average bubbles per second or “BPS” for Co2 distribution.
Install Co2 Bubble counter or Beetle Counter on the side of the aquarium with Co2 tubing. Place after the check valve but before the diffuser in your Co2 setup.
