The CO2 regulator is one of the most important aspects of any CO2 system.  The pressure in a gas cylinder can be over 700 psi which is way too high for safe usage in any application. The regulator plays the crucial role of allowing just enough CO2 to dispense safely through the airline tubing, through the diffuser and into your aquarium.
