Bubble Counters
CO2 bubble counters allow you to monitor the flowrate of CO2 into your aquarium. Being able to visually monitor the CO2 flowrate helps detect possible drifts due to faulty regulators or needle valves. The bubble counters are attached inline with the CO2 line and secured to the outside of the aquarium. Typical bubble counters allow the user to monitor CO2 flowrates up to 4-5 bubbles per second. Flowrates higher than this makes counting, and therefore monitoring, difficult to impossible. Cal Aqua Labs’ Double Counter addresses this issue by offering a unique dual-function design that allows monitoring of both low and high CO2 flowrates within one unit.
Double Counter
Product code: 13001
The Double Counter functions both as a normal-flow and a high-flow bubble counter in one elegant design. For small to medium-sized tanks where CO2 bubble rates are not as high, the normal flow mode creates bubbles similar to typical bubble counters. This mode can be used to monitor flowrates up to 4-5 bubbles per second.
For higher flowrates, simply invert the counter. The tapered design gently guides the bubbles upwards and allows larger bubbles to be formed, effectively slowing down the bubble rate. This allows high CO2 flowrates (up to 10-15 bubbles per second when measured on a typical bubble counter) to be easily monitored.
Note: More information, including how to relate the high-flow bubble rate to the normal-flow rate, can be found in the FAQ section. Always install a check valve below the bubble counter to prevent water from flowing back into the regulator.
Supplied with 2 suction cups. Check valve not included.
Approximate size: 9.5cm x 1.7cm (LxW)
Double Counter ER
Product code: 13002
The Double Counter ER functions exactly the same as the original Double Counter but has an external port for quick and easy filling.
Over time, water level inside bubble counters will evaporate due to the constant stream of dry CO2 passing through. This requires the user to refill the liquid back to its original level. Traditional bubble counter designs require the users to disconnect the CO2 line from the checker each time it is refilled, which is inconvenient and may eventually loosen the tubing leading to CO2 leaks.
The Double Counter ER can be quickly filled simply by removing the silicone plug, fill, and reinstall the plug without having to disconnect any tubing. It is as easy as that!
