The 10 Best CO2 Regulators
This wiki has been updated 11 times since it was first published in June of 2016. 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 their usefulness for a variety of other applications, including hydroponics — where they can help fertilize the air to increase yield and speed up plant maturation in grow houses — as well as aquariums and paintball. When users buy our independently chosen editorial choices, we may earn commissions to help fund the Wiki. Skip to the best co2 regulator on Amazon.
