Aquarium CO₂ Regulator

The Blue Zone Aquarium CO₂ Regulator is a single stage unit designed for planted aquariums. It connects securely to standard CO₂ cylinders and delivers stable output for diffusers, bubble counters, or splitters. We use these regulators daily in our own Aquariums, where they operate continuously without issues.

The regulator is constructed from solid metal components and requires a wrench to tighten onto the CO₂ cylinder, ensuring a secure, leak resistant connection. It features a standard M10 threaded outlet along with a hose barb fitting, allowing direct connection to CO₂ tubing or the use of accessories such as threaded bubble counter ( 1 included) , inline bubble counters, or M10 CO₂ splitters.
