CO₂ Bubble Counters

A CO₂ Bubble Counter is a simple and visual tool for measuring the amount of Carbon Dioxide (CO₂) entering the aquarium. The bubble counter allows you to count the number of bubbles per second leaving the regulator and entering the aquarium, as the bubbles pass through the glass reservoir. With this knowledge, you can make more informed decisions about the supply of CO₂ to your planted aquarium, and understand the effects of CO₂ levels on the aquarium ecosystem as a whole.
