Chihiros Bubble Counter

The Quick Twist CO₂ Bubble Counter & Check Valve is a durable, precision tool designed to make CO₂ injection management simple and reliable. Constructed from high-quality aluminium alloy and clear acrylic, it allows aquarists to easily monitor their CO₂ injection rate while protecting their equipment from backflow.

When your CO₂ regulator is open, you can accurately calculate your injection rate by counting the number of bubbles passing through the counter per minute. The built-in check valve prevents water from siphoning back into sensitive CO₂ components such as regulators and solenoids, providing peace of mind and long-term system protection.

This compact inline bubble counter is easy to read, easy to maintain, and features a tried-and-tested design that delivers reliable performance without the bulk or cost of larger monitoring systems. Simply unscrew one end, fill it with water (or a coloured solution for better visibility), and you’re ready to go.
