The Chihiros CO₂ Pressure Regulator reduces the pressure of a CO₂ gas cylinder from 57 bar and makes the gas usable for aquaristics. The W21.8 thread makes the pressure regulator suitable for use with reusable CO₂-cylinders. The precise adjustment options and excellent build quality make it possible to precisely adjust the CO₂-supply for aquariums of all kinds. Aquascapes and also professional applications such as grow tanks can be set to precisely defined CO₂ concentrations with the help of Chihiro's pressure regulator. Thanks to its unobtrusive design and compact construction, this pressure regulator also visually matches reduced, minimalist designs such as an Iwagumi. Due to its attractive price and ease of use, the Chihiros pressure regulator can be set up and operated by inexperienced aquarium enthusiasts, but also offers great potential for professional aquascapers.
