Overview
The CO₂ Bubble Counter with Built-in Check Valve is a precision device that connects directly to your CO₂ regulator via a tube-to-regulator screw-on adapter. It allows you to monitor CO₂ dosing accurately while the integrated check valve protects sensitive solenoids and regulators from water backflow.
Key Features
- Tube-to-regulator fitting: Attaches directly to the regulator’s needle valve and secures CO₂ tubing at the outlet.
- Built-in check valve: Prevents aquarium water from siphoning back into the regulator and solenoid—critical safety feature .
- Clear chamber: Transparent water reservoir filled ~¾ to allow accurate bubble count and easy visual monitoring.
- Durable construction: Often made of aluminium or aluminium-core with PC or acrylic—solid build designed for long-term use .
- Easy to install: Vertical orientation simplifies setup—screw into the regulator, fill with water, attach CO₂ tubing, and go.
