We spent 25 hours on research, videography, and editing, to review the top choices for this wiki. While we have to admit that our favorite use for these CO2 regulators is ensuring the perfect carbonation level for home brewed beer, we are happy to acknowledge that they are also useful for a variety of other applications, including adding CO2 to grow houses to increase the yield and speed up plant maturation, and for aquariums. When users buy our independently chosen editorial picks, we may earn commissions to support our work. Skip to the best co2 regulator on Amazon.

A wandering writer who spends as much time on the road as behind the computer screen, Brett can either be found hacking furiously away at the keyboard or perhaps enjoying a whiskey and coke on some exotic beach, sometimes both simultaneously, usually with a four-legged companion by his side. He hopes to one day become a modern day renaissance man.
