Aquarium CO2 Regulator With Bubble Counter

This is a high-quality CO2 regulator with a bubble counter. The body is made of aluminum alloy, with stainless steel gauges and copper electroplated needle valves. It’s one of the most durable units available, and it can withstand extreme temperatures.

The high-precision needle valve includes a bubble valve. It is so precise that you can set it to go as low as just one bubble every five seconds. To help prevent any backflow from occurring, it also includes a check valve to protect the solenoid.

This solenoid can be plugged into a timer of your choosing for automatic functionality. This unit remains cool during operation, and it is very quiet. In addition, it consumes only 2.5 watts, making it very energy efficient.
