The CAL Aqua Labs Double Counter functions as both a normal and high supply CO2 bubble counter, combined in one elegant design. Easily determine how much CO2 is added to the aquarium. For a small to medium-sized aquarium, where the number of CO2 bubbles per second are not that many, the normal setting is suitable. The bubbles are of the same size as other bubble counters. This mode is suitable for counting up to 4 to 5 bubbles per second.
The CO2 Double Counter can be turned over for a larger CO2 supply. The tapered design gradually guides the bubbles upwards, forming larger bubbles. A smart solution to slow down the flow of bubbles, making them easier to count. CO2 supply of up to 10 to 15 bubbles per second (compared to a standard CO2 bubble counter) can be counted.
The CO2 bubble counter is supplied with 2 clear transparent suction cups. This allows it to be attached to the side of the aquarium. Excluding Check Valve. Dimensions approx. 95x17mm (HxW)
Always use a Check Valve to prevent water from entering the CO2 system.
