Description
Take complete control of your aquatic environment with this all-in-one solution for CO2 management. This unit combines a high-quality solenoid with an integrated precision needle valve, allowing you to not only automate your gas cycles but also fine-tune the exact flow rate for consistent, accurate dosing.
The 12v DC solenoid is designed for long-term reliability, providing cool and silent operation without the humming associated with traditional valves. It comes with its own mains power transformer, making it a simple plug-and-play addition to your aquarium setup.
On the output side, the precision needle valve allows for micro-adjustments, ensuring you can maintain the perfect bubble count for your specific tank size. The unit features robust stainless steel compression collars that fit both 4mm and 6mm hosing for a leak-proof seal.
For those connecting this unit directly to a regulator, we strongly advise using a 24mm or 57mm metal extension. Using standard PVC or Polyurethane tubing in the space between your regulator and the solenoid will cause the tubing to pop with significant force once the solenoid closes and pressure builds. A metal extension ensures a solid, secure connection that eliminates this hazard.

14th Aug 2025Solid build quality and the needle valve lets me adjust CO2 levels just right for my tank. No noise and stays cool, so I don’t have to worry about it running all day.
