How does a bubble counter work?
Bubble Counter - A bubble counter allows you to monitor the rate of CO2 entering your aquarium. It is an external piece of equipment that should be added in-line to your filter tubing. Whilst adjusting your regulator, you can use the bubble counter to count the bubbles entering your aquarium one by one.
