Reliable CO₂ Regulation in One Compact Accessory

ISTA 2 in1 CO₂ Bubble Counter and Check Valve is an essential component for planted aquariums using CO₂ systems. This clever dual-function device simplifies your setup by integrating a visual bubble counter with a protective check valve that prevents backflow and pressure damage.

The spring-type check valve ensures water does not reverse flow into your regulator, while the built-in bubble counter allows you to monitor CO₂ flow with precision. A secure pipe fasten screw node keeps tubing firmly in place, reducing the risk of accidental disconnection.
