I prefer in-line needle valves to ones that screw directly to the regulator.
Simply put, with in-line valve(s) you can meter more than one aquarium
individually from one CO2 cylinder.  With a needle valve directly attached
to the regulator, you can only set one metering rate, even if you feed CO2
to more than one tank.
