The CalAquaLabs Double Counter for Aquariums combines a high-flow CO2 bubble counter with an elegant design. Easily determine how much CO2 will be added to the aquarium. The normal position is appropriate for a small to medium aquarium with a low number of CO2 bubbles per second. Here are the same-sized bubbles as the other bellentellers. This mode can count up to four or five bubbles per second.
The CO2 can Double Counter is reversed to increase CO2 supply. The tapered design accompanied the bubbles as they grew larger as they moved up. A clever way to slow down the bellenstroom and make them easier to count. CO2 supply can be counted at 10 to 15 calls per second (in comparison to a standard CO2 bubble counter). Two clear transparent suction cups are included with the CO2 bubble counter. This allows for confirmation on the aquarium's side.
