The Ultimate Dual Stage Co2 regulator boasts an impressive and convenient bubble counter manifold that allows for easy injection of Co2 into multiple aquariums. Simply add on multiple manifolds to the regulator and adjust the individual needle valves to the desired bubble count. Our manifolds are made from high quality stainless steel and materials, ensuring that you will always get consistent Co2. With an adjustable output pressure, you are protected from end of tank Co2 dumps. The high-precision needle valve allows for maximum fine tuning of Co2 up to as low as 1 bubble per 10 seconds. Our 12v DC magnetic solenoids are designed to shut off completely when Co2 injection isn’t required.

All our regulators are designed to fit AU/NZ’s Co2 cylinder threads which follows the W21.8 European standard.
